This class represents the manifest entry of a JAR file. getMainAttributes( ) returns an Attributes object that represents the manifest attributes that apply to the entire JAR file. getAttributes( ) returns an Attributes object that represents the manifest attributes specified for a single file in the JAR file. getEntries( ) returns a java.util.Map that maps the names of entries in the JAR file to the Attributes objects associated with those entries. getEnTRies( ) returns the Map object used internally by the Manifest. You can edit the contents of the Manifest by adding, deleting, or editing entries in the Map. read( ) reads manifest entries from an input stream, merging them into the current set of entries. write( ) writes the Manifest out to the specified output stream.
