instance, if specified, ornull
otherwise.- Specified by:
getDefaultValue
in interfaceOpenMBeanParameterInfo
- Returns:
- the default value.
-
getLegalValues
Returns an unmodifiable Set of legal values for the parameter described by thisOpenMBeanParameterInfoSupport
instance, if specified, ornull
otherwise.- Specified by:

instance, if specified, ornull
otherwise.- Specified by:
getMinValue
in interfaceOpenMBeanParameterInfo
- Returns:
- the minimum value.
-
getMaxValue
Returns the maximal value for the parameter described by thisOpenMBeanParameterInfoSupport
instance, if specified, ornull
otherwise.- Specified by:
getMaxValue
in interfaceOpenMBeanParameterInfo
- Returns:

public boolean hasDefaultValue()Returnstrue
if thisOpenMBeanParameterInfoSupport
instance specifies a non-null default value for the described parameter,false
otherwise.- Specified by:
hasDefaultValue
in interfaceOpenMBeanParameterInfo
- Returns:
- true if there is a default value.
-
hasLegalValues
public boolean hasLegalValues()Returnstrue
if thisOpenMBeanParameterInfoSupport
instance specifies a non-null set of legal values for the described parameter,false
otherwise.- Specified by:
hasLegalValues
in interfaceOpenMBeanParameterInfo
- Returns:
- true if there is a set of legal values.
-

public boolean hasMinValue()Returnstrue
if thisOpenMBeanParameterInfoSupport
instance specifies a non-null minimal value for the described parameter,false
otherwise.- Specified by:
hasMinValue
in interfaceOpenMBeanParameterInfo
- Returns:
- true if there is a minimum value.
-

instance specifies a non-null maximal value for the described parameter,false
otherwise.- Specified by:

Tests whetherobj
is a valid value for the parameter described by thisOpenMBeanParameterInfo
instance.- Specified by:
isValue

- Parameters:
obj
- the object to be tested.- Returns:

-
equals
Compares the specified
obj
parameter with thisOpenMBeanParameterInfoSupport
instance for equality.Returns
true
if and only if all of the following statements are true:obj
is non null,obj
also implements theOpenMBeanParameterInfo
interface,- their names are equal
- their open types are equal
- their default, min, max and legal values are equal.
equals
method works properly forobj
parameters which are different implementations of theOpenMBeanParameterInfo
interface.If
obj
also implementsDescriptorRead
, then itsgetDescriptor()
method must also return the same value as for this object.- Specified by:
equals
in interfaceOpenMBeanParameterInfo
- Overrides:
equals
in classMBeanParameterInfo
- Parameters:
obj
- the object to be compared for equality with thisOpenMBeanParameterInfoSupport
instance.- Returns:
true
if the specified object is equal to thisOpenMBeanParameterInfoSupport
instance.- See Also:
Object.hashCode()
,HashMap
-
hashCode
public int hashCode()Returns the hash code value for this
OpenMBeanParameterInfoSupport
instance.The hash code of an
OpenMBeanParameterInfoSupport
instance is the sum of the hash codes of all elements of information used inequals
comparisons (ie: its name, its open type, its default, min, max and legal values, and its Descriptor).This ensures that
t1.equals(t2)
implies thatt1.hashCode()==t2.hashCode()
for any twoOpenMBeanParameterInfoSupport
instancest1
andt2
, as required by the general contract of the methodObject.hashCode()
.However, note that another instance of a class implementing the
OpenMBeanParameterInfo
interface may be equal to thisOpenMBeanParameterInfoSupport
instance as defined byequals(java.lang.Object)
, but may have a different hash code if it is calculated differently.As
OpenMBeanParameterInfoSupport
instances are immutable, the hash code for this instance is calculated once, on the first call tohashCode
, and then the same value is returned for subsequent calls.- Specified by:
hashCode
in interfaceOpenMBeanParameterInfo
- Overrides:
hashCode
in classObject
- Returns:
- the hash code value for this
OpenMBeanParameterInfoSupport
instance - See Also:
Object.equals(java.lang.Object)
,System.identityHashCode(java.lang.Object)
-
toString
Returns a string representation of thisOpenMBeanParameterInfoSupport
instance.The string representation consists of the name of this class (i.e.
javax.management.openmbean.OpenMBeanParameterInfoSupport
), the string representation of the name and open type of the described parameter, the string representation of its default, min, max and legal values and the string representation of its descriptor.As
OpenMBeanParameterInfoSupport
instances are immutable, the string representation for this instance is calculated once, on the first call totoString
, and then the same value is returned for subsequent calls.- Specified by:
toString
in interfaceOpenMBeanParameterInfo
- Overrides:
toString
in classObject
- Returns:
- a string representation of this
OpenMBeanParameterInfoSupport
instance.
