Class SimpleNode

java.lang.Object
edu.internet2.middleware.grouperClientExt.org.apache.commons.jexl2.parser.SimpleNode
All Implemented Interfaces:
Node
Direct Known Subclasses:
JexlNode
public class SimpleNode extends Object implements Node
A class originally generated by JJTree with the following JavaCCOptions: MULTI=true,NODE_USES_PARSER=true,VISITOR=true,TRACK_TOKENS=false,NODE_PREFIX=AST,NODE_EXTENDS=,NODE_FACTORY= Works around issue https://javacc.dev.java.net/issues/show_bug.cgi?id=227 As soon as this issue if fixed and the maven plugin uses the correct version of Javacc, this class can go away. The technical goal is to ensure every reference made in the parser was to a JexlNode; unfortunately, as in javacc 4.1, it still uses a SimpleNode reference in the generated ParserVisitor. Besides, there is no need to keep the parser around in the node. The functional goal is to a allow a volatile value in the node so it can serve as a last evaluation cache even in multi-threaded executions.
