Method Detail

match

public abstract boolean match(T node)

Returns true if the input node matches this pattern

Parameters:

node - - node to match

Returns:

true if the node matches the pattern, false otherwise

matchWithResult

public java.lang.Object matchWithResult(T node)

Returns result associated with the match

Parameters:

node - node to match

Returns:

null if not matched, TRUE if there is a match but no other result associated with the match. Any other value is treated as the result value of the match.
