All Implemented Interfaces:
Parser

This class is similar to Parser except that it stores ending positions for the tree nodes.

This is NOT part of any supported API. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice.

Field Summary
Map<JCTree, Integer>	endPositions	A hashtable to store ending positions of source ranges indexed by the tree nodes. Defined only if option flag genEndPos is set.

Constructor:
public EndPosParser(ParserFactory fac, Lexer S, boolean keepDocComments, boolean keepLineMap) { super(fac, S, keepDocComments, keepLineMap); this.S = S; endPositions = new HashMap< JCTree,Integer >(); }
