Class JDOQLCodeGeneration

java.lang.Object

antlr.TreeParser

com.sun.jdo.spi.persistence.support.ejb.ejbqlc.JDOQLCodeGeneration

All Implemented Interfaces:

JDOQLCodeGenerationTokenTypes

public class JDOQLCodeGeneration
extends antlr.TreeParser
implements JDOQLCodeGenerationTokenTypes

This class defines the semantic analysis of the EJBQL compiler. Input of this pass is the AST as produced by the parser, that consists of EJBQLAST nodes. The result is a typed EJBQLAST tree.
