Names
Each name passed as an argument to aDirContext
method is relative
to that context. The empty name is used to name the context itself.
The name parameter may never be null.
Most of the methods have overloaded versions with one taking a
Name
parameter and one taking a String
.
These overloaded versions are equivalent in that if
the Name
and String
parameters are just
different representations of the same name, then the overloaded
versions of the same methods behave the same.
In the method descriptions below, only one version is documented.
The second version instead has a link to the first: the same
documentation applies to both.
See Context
for a discussion on the interpretation of the
name argument to the Context
methods. These same rules
apply to the name argument to the DirContext
methods.
Attribute Models
There are two basic models of what attributes should be associated with. First, attributes may be directly associated with a DirContext object. In this model, an attribute operation on the named object is roughly equivalent to a lookup on the name (which returns the DirContext object), followed by the attribute operation invoked on the DirContext object in which the caller supplies an empty name. The attributes can be viewed as being stored along with the object (note that this does not imply that the implementation must do so).The second model is that attributes are associated with a name (typically an atomic name) in a DirContext. In this model, an attribute operation on the named object is roughly equivalent to a lookup on the name of the parent DirContext of the named object, followed by the attribute operation invoked on the parent in which the caller supplies the terminal atomic name. The attributes can be viewed as being stored in the parent DirContext (again, this does not imply that the implementation must do so). Objects that are not DirContexts can have attributes, as long as their parents are DirContexts.
JNDI support both of these models. It is up to the individual service providers to decide where to "store" attributes. JNDI clients are safest when they do not make assumptions about whether an object's attributes are stored as part of the object, or stored within the parent object and associated with the object's name.
Attribute Type Names
In thegetAttributes()
and search()
methods,
you can supply the attributes to return by supplying a list of
attribute names (strings).
The attributes that you get back might not have the same names as the
attribute names you have specified. This is because some directories
support features that cause them to return other attributes. Such
features include attribute subclassing, attribute name synonyms, and
attribute language codes.
In attribute subclassing, attributes are defined in a class hierarchy. In some directories, for example, the "name" attribute might be the superclass of all name-related attributes, including "commonName" and "surName". Asking for the "name" attribute might return both the "commonName" and "surName" attributes.
With attribute type synonyms, a directory can assign multiple names to the same attribute. For example, "cn" and "commonName" might both refer to the same attribute. Asking for "cn" might return the "commonName" attribute.
Some directories support the language codes for attributes. Asking such a directory for the "description" attribute, for example, might return all of the following attributes:
- description
- description;lang-en
- description;lang-de
- description;lang-fr
Operational Attributes
Some directories have the notion of "operational attributes" which are attributes associated with a directory object for administrative purposes. An example of operational attributes is the access control list for an object.
In the getAttributes()
and search()
methods,
you can specify that all attributes associated with the requested objects
be returned by supply null
as the list of attributes to return.
The attributes returned do not include operational attributes.
In order to retrieve operational attributes, you must name them explicitly.
Named Context
There are certain methods in which the name must resolve to a context
(for example, when searching a single level context). The documentation
of such methods
use the term named context to describe their name parameter.
For these methods, if the named object is not a DirContext,
NotContextException
is thrown.
Aside from these methods, there is no requirement that the
named object be a DirContext.
Parameters
An Attributes
, SearchControls
, or array object
passed as a parameter to any method will not be modified by the
service provider. The service provider may keep a reference to it
for the duration of the operation, including any enumeration of the
method's results and the processing of any referrals generated.
The caller should not modify the object during this time.
An Attributes
object returned by any method is owned by
the caller. The caller may subsequently modify it; the service
provider will not.
Exceptions
All the methods in this interface can throw a NamingException or any of its subclasses. See NamingException and their subclasses for details on each exception.

createSubcontext
Creates and binds a new context, along with associated attributes. This method creates a new subcontext with the given name, binds it in the target context (that named by all but terminal atomic component of the name), and associates the supplied attributes with the newly created object. All intermediate and target contexts must already exist. Ifattrs
is null, this method is equivalent toContext.createSubcontext()
.- Parameters:
name
- the name of the context to create; may not be emptyattrs
- the attributes to associate with the newly created context- Returns:
- the newly created context
- Throws:
NameAlreadyBoundException

- the newly created context
- Throws:
NameAlreadyBoundException
- if the name is already boundInvalidAttributesException
- ifattrs
does not contain all the mandatory attributes required for creationNamingException

-
getSchema
Retrieves the schema associated with the named object. The schema describes rules regarding the structure of the namespace and the attributes stored within it. The schema specifies what types of objects can be added to the directory and where they can be added; what mandatory and optional attributes an object can have. The range of support for schemas is directory-specific.This method returns the root of the schema information tree that is applicable to the named object. Several named objects (or even an entire directory) might share the same schema.
Issues such as structure and contents of the schema tree, permission to modify to the contents of the schema tree, and the effect of such modifications on the directory are dependent on the underlying directory.
- Parameters:
name
- the name of the object whose schema is to be retrieved- Returns:
- the schema associated with the context; never null
- Throws:
OperationNotSupportedException
- if schema not supportedNamingException
- if a naming exception is encountered
-
getSchema
Retrieves the schema associated with the named object. SeegetSchema(Name)
for details.- Parameters:
name
- the name of the object whose schema is to be retrieved- Returns:
- the schema associated with the context; never null
- Throws:
OperationNotSupportedException
- if schema not supportedNamingException
- if a naming exception is encountered
-
getSchemaClassDefinition
Retrieves a context containing the schema objects of the named object's class definitions.One category of information found in directory schemas is class definitions. An "object class" definition specifies the object's type and what attributes (mandatory and optional) the object must/can have. Note that the term "object class" being referred to here is in the directory sense rather than in the Java sense. For example, if the named object is a directory object of "Person" class,
getSchemaClassDefinition()
would return aDirContext
representing the (directory's) object class definition of "Person".The information that can be retrieved from an object class definition is directory-dependent.
Prior to JNDI 1.2, this method returned a single schema object representing the class definition of the named object. Since JNDI 1.2, this method returns a
DirContext
containing all of the named object's class definitions.- Parameters:
name
- the name of the object whose object class definition is to be retrieved- Returns:
- the
DirContext
containing the named object's class definitions; never null - Throws:
OperationNotSupportedException
- if schema not supportedNamingException
- if a naming exception is encountered
-
getSchemaClassDefinition
Retrieves a context containing the schema objects of the named object's class definitions. SeegetSchemaClassDefinition(Name)
for details.- Parameters:
name
- the name of the object whose object class definition is to be retrieved- Returns:
- the
DirContext
containing the named object's class definitions; never null - Throws:
OperationNotSupportedException
- if schema not supportedNamingException
- if a naming exception is encountered
-
search
NamingEnumeration<SearchResult> search(Name name, Attributes matchingAttributes, String[] attributesToReturn) throws NamingException Searches in a single context for objects that contain a specified set of attributes, and retrieves selected attributes. The search is performed using the defaultSearchControls
settings.For an object to be selected, each attribute in
matchingAttributes
must match some attribute of the object. IfmatchingAttributes
is empty or null, all objects in the target context are returned.An attribute A1 in
matchingAttributes
is considered to match an attribute A2 of an object if A1 and A2 have the same identifier, and each value of A1 is equal to some value of A2. This implies that the order of values is not significant, and that A2 may contain "extra" values not found in A1 without affecting the comparison. It also implies that if A1 has no values, then testing for a match is equivalent to testing for the presence of an attribute A2 with the same identifier.The precise definition of "equality" used in comparing attribute values is defined by the underlying directory service. It might use the
Object.equals
method, for example, or might use a schema to specify a different equality operation. For matching based on operations other than equality (such as substring comparison) use the version of thesearch
method that takes a filter argument.When changes are made to this
DirContext
, the effect on enumerations returned by prior calls to this method is undefined.If the object does not have the attribute specified, the directory will ignore the nonexistent attribute and return the requested attributes that the object does have.
A directory might return more attributes than was requested (see Attribute Type Names in the class description), but is not allowed to return arbitrary, unrelated attributes.
See also Operational Attributes in the class description.
- Parameters:
name
- the name of the context to searchmatchingAttributes
- the attributes to search for. If empty or null, all objects in the target context are returned.attributesToReturn
- the attributes to return. null indicates that all attributes are to be returned; an empty array indicates that none are to be returned.- Returns:
- a non-null enumeration of
SearchResult
objects. EachSearchResult
contains the attributes identified byattributesToReturn
and the name of the corresponding object, named relative to the context named byname
. - Throws:
NamingException
- if a naming exception is encountered- See Also:

-
search
NamingEnumeration<SearchResult> search(Name name, Attributes matchingAttributes) throws NamingException Searches in a single context for objects that contain a specified set of attributes. This method returns all the attributes of such objects. It is equivalent to supplying null as theattributesToReturn
parameter to the methodsearch(Name, Attributes, String[])
.
Seesearch(Name, Attributes, String[])
for a full description.- Parameters:
name
- the name of the context to searchmatchingAttributes
- the attributes to search for- Returns:
- an enumeration of
SearchResult
objects - Throws:
NamingException
- if a naming exception is encountered- See Also:
-
search
NamingEnumeration<SearchResult> search(String name, Attributes matchingAttributes) throws NamingException Searches in a single context for objects that contain a specified set of attributes. Seesearch(Name, Attributes)
for details.- Parameters:
name
- the name of the context to searchmatchingAttributes
- the attributes to search for- Returns:
- an enumeration of
SearchResult
objects - Throws:
NamingException
- if a naming exception is encountered
-
search
NamingEnumeration<SearchResult> search(Name name, String filter, SearchControls cons) throws NamingException Searches in the named context or object for entries that satisfy the given search filter. Performs the search as specified by the search controls.The format and interpretation of
filter
follows RFC 2254 with the following interpretations forattr
andvalue
mentioned in the RFC.attr
is the attribute's identifier.value
is the string representation the attribute's value. The translation of this string representation into the attribute's value is directory-specific.For the assertion "someCount=127", for example,
attr
is "someCount" andvalue
is "127". The provider determines, based on the attribute ID ("someCount") (and possibly its schema), that the attribute's value is an integer. It then parses the string "127" appropriately.Any non-ASCII characters in the filter string should be represented by the appropriate Java (Unicode) characters, and not encoded as UTF-8 octets. Alternately, the "backslash-hexcode" notation described in RFC 2254 may be used.
If the directory does not support a string representation of some or all of its attributes, the form of
search
that accepts filter arguments in the form of Objects can be used instead. The service provider for such a directory would then translate the filter arguments to its service-specific representation for filter evaluation. Seesearch(Name, String, Object[], SearchControls)
.RFC 2254 defines certain operators for the filter, including substring matches, equality, approximate match, greater than, less than. These operators are mapped to operators with corresponding semantics in the underlying directory. For example, for the equals operator, suppose the directory has a matching rule defining "equality" of the attributes in the filter. This rule would be used for checking equality of the attributes specified in the filter with the attributes of objects in the directory. Similarly, if the directory has a matching rule for ordering, this rule would be used for making "greater than" and "less than" comparisons.
Not all of the operators defined in RFC 2254 are applicable to all attributes. When an operator is not applicable, the exception
InvalidSearchFilterException
is thrown.The result is returned in an enumeration of
SearchResult
s. EachSearchResult
contains the name of the object and other information about the object (see SearchResult). The name is either relative to the target context of the search (which is named by thename
parameter), or it is a URL string. If the target context is included in the enumeration (as is possible whencons
specifies a search scope ofSearchControls.OBJECT_SCOPE
orSearchControls.SUBSTREE_SCOPE
), its name is the empty string. TheSearchResult
may also contain attributes of the matching object if thecons
argument specified that attributes be returned.If the object does not have a requested attribute, that nonexistent attribute will be ignored. Those requested attributes that the object does have will be returned.
A directory might return more attributes than were requested (see Attribute Type Names in the class description) but is not allowed to return arbitrary, unrelated attributes.
See also Operational Attributes in the class description.

search
NamingEnumeration<SearchResult> search(String name, String filter, SearchControls cons) throws NamingException Searches in the named context or object for entries that satisfy the given search filter. Performs the search as specified by the search controls. Seesearch(Name, String, SearchControls)
for details.- Parameters:
name
- the name of the context or object to searchfilter
- the filter expression to use for the search; may not be nullcons
- the search controls that control the search. If null, the default search controls are used (equivalent to(new SearchControls())
).- Returns:
- an enumeration of
SearchResult
s for the objects that satisfy the filter. - Throws:
InvalidSearchFilterException

- if the search controls contain invalid settingsNamingException
- if a naming exception is encountered
-
search
NamingEnumeration<SearchResult> search(Name name, String filterExpr, Object[] filterArgs, SearchControls cons) throws NamingException Searches in the named context or object for entries that satisfy the given search filter. Performs the search as specified by the search controls.The interpretation of
filterExpr
is based on RFC 2254. It may additionally contain variables of the form{i}
-- wherei
is an integer -- that refer to objects in thefilterArgs
array. The interpretation offilterExpr
is otherwise identical to that of thefilter
parameter of the methodsearch(Name, String, SearchControls)
.When a variable
{i}
appears in a search filter, it indicates that the filter argumentfilterArgs[i]
is to be used in that place. Such variables may be used wherever an attr, value, or matchingrule production appears in the filter grammar of RFC 2254, section 4. When a string-valued filter argument is substituted for a variable, the filter is interpreted as if the string were given in place of the variable, with any characters having special significance within filters (such as'*'
) having been escaped according to the rules of RFC 2254.For directories that do not use a string representation for some or all of their attributes, the filter argument corresponding to an attribute value may be of a type other than String. Directories that support unstructured binary-valued attributes, for example, should accept byte arrays as filter arguments. The interpretation (if any) of filter arguments of any other type is determined by the service provider for that directory, which maps the filter operations onto operations with corresponding semantics in the underlying directory.
This method returns an enumeration of the results. Each element in the enumeration contains the name of the object and other information about the object (see
SearchResult
). The name is either relative to the target context of the search (which is named by thename
parameter), or it is a URL string. If the target context is included in the enumeration (as is possible whencons
specifies a search scope ofSearchControls.OBJECT_SCOPE
orSearchControls.SUBSTREE_SCOPE
), its name is the empty string.The
SearchResult
may also contain attributes of the matching object if thecons
argument specifies that attributes be returned.If the object does not have a requested attribute, that nonexistent attribute will be ignored. Those requested attributes that the object does have will be returned.
A directory might return more attributes than were requested (see Attribute Type Names in the class description) but is not allowed to return arbitrary, unrelated attributes.
If a search filter with invalid variable substitutions is provided to this method, the result is undefined. When changes are made to this DirContext, the effect on enumerations returned by prior calls to this method is undefined.
