Enclosing class:

UnBufferedTreeNodeStream

extends java.lang.Object

When walking ahead with cyclic DFA or for syntactic predicates, we need to record the state of the tree node stream. This class wraps up the current state of the UnBufferedTreeNodeStream. Calling mark() will push another of these on the markers stack.
