Class OgnlParser

java.lang.Object

ognl.OgnlParser

All Implemented Interfaces:

OgnlParserConstants, OgnlParserTreeConstants

public class OgnlParser
extends java.lang.Object
implements OgnlParserTreeConstants, OgnlParserConstants

OgnlParser is a JavaCC parser class; it translates OGNL expressions into abstract syntax trees (ASTs) that can then be interpreted by the getValue and setValue methods.
