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).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().
