Field Details

EMPTY

public static final Resourcepart EMPTY

This empty resource part is the part that is represented by the empty String. This is useful in cases where you have a collection of Resourceparts that does not allow null values, but you want to deal with the "no resource" case.

public static Resourcepart fromOrThrowUnchecked(CharSequence cs)

Like from(String) but does throw an unchecked IllegalArgumentException instead of a XmppStringprepException.
