Method Detail |

public Attributes getMainAttributes()
public Map<String,Attributes> getEntries()
public Attributes getAttributes(String name)
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() .
