Package Summary  Overview Summary

class:Manifest [NONE]

  • All Implemented Interfaces:
    Cloneable

    public class Manifest
    extends Object
    implements Cloneable
    
    The Manifest class is used to maintain Manifest entry names and their associated Attributes. There are main Manifest Attributes as well as per-entry Attributes. For information on the Manifest format, please see the Manifest format specification .
    Since:
    1.2
    See Also:
    Attributes

constructor:<init>() [NONE]

  • Manifest

    public Manifest()
    Constructs a new, empty Manifest.

constructor:<init>(java.io.InputStream) [NONE]

  • Manifest

    public Manifest​(InputStream is)
             throws IOException
    
    Constructs a new Manifest from the specified input stream.
    Parameters:
    is - the input stream containing manifest data
    Throws:
    IOException - if an I/O error has occurred

constructor:<init>(java.util.jar.Manifest) [NONE]

  • Manifest

    public Manifest​(Manifest man)
    Constructs a new Manifest that is a copy of the specified Manifest.
    Parameters:
    man - the Manifest to copy

method:getMainAttributes() [NONE]

  • getMainAttributes

    public Attributes getMainAttributes()
    Returns the main Attributes for the Manifest.
    Returns:
    the main Attributes for the Manifest

method:getEntries() [NONE]

  • getEntries

    public Map<String,Attributes> getEntries()
    Returns a Map of the entries contained in this Manifest. Each entry is represented by a String name (key) and associated Attributes (value). The Map permits the null key, but no entry with a null key is created by read(java.io.InputStream), nor is such an entry written by using write(java.io.OutputStream).
    Returns:
    a Map of the entries contained in this Manifest

method:getAttributes(java.lang.String) [NONE]

  • getAttributes

    public Attributes getAttributes​(String name)
    Returns the Attributes for the specified entry name. This method is defined as:
          return (Attributes)getEntries().get(name)
     
    Though null is a valid name, when getAttributes(null) is invoked on a Manifest obtained from a jar file, null will be returned. While jar files themselves do not allow null-named attributes, it is possible to invoke getEntries() on a Manifest, and on that result, invoke put with a null key and an arbitrary value. Subsequent invocations of getAttributes(null) will return the just-put value.

    Note that this method does not return the manifest's main attributes; see getMainAttributes().

    Parameters:
    name - entry name
    Returns:
    the Attributes for the specified entry name

method:clear() [NONE]

  • clear

    public void clear()
    Clears the main Attributes as well as the entries in this Manifest.

method:write(java.io.OutputStream) [NONE]

  • write

    public void write​(OutputStream out)
               throws IOException
    
    Writes the Manifest to the specified OutputStream. Attributes.Name.MANIFEST_VERSION must be set in MainAttributes prior to invoking this method.
    Parameters:
    out - the output stream
    Throws:
    IOException - if an I/O error has occurred
    See Also:
    getMainAttributes()

method:read(java.io.InputStream) [NONE]

  • read

    public void read​(InputStream is)
              throws IOException
    
    Reads the Manifest from the specified InputStream. The entry names and attributes read will be merged in with the current manifest entries.
    Parameters:
    is - the input stream
    Throws:
    IOException - if an I/O error has occurred

method:equals(java.lang.Object) [NONE]

  • equals

    public boolean equals​(Object o)
    Returns true if the specified Object is also a Manifest and has the same main Attributes and entries.
    Overrides:
    equals in class Object
    Parameters:
    o - the object to be compared
    Returns:
    true if the specified Object is also a Manifest and has the same main Attributes and entries
    See Also:
    Object.hashCode(), HashMap

method:hashCode() [NONE]

method:clone() [NONE]

  • clone

    public Object clone()
    Returns a shallow copy of this Manifest. The shallow copy is implemented as follows:
         public Object clone() { return new Manifest(this); }
     
    Overrides:
    clone in class Object
    Returns:
    a shallow copy of this Manifest

    Cloneable
