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