com.sun.jdo.spi.persistence.support.ejb.ejbqlc
Class Semantic

java.lang.Object
  extended by antlr.TreeParser
      extended by com.sun.jdo.spi.persistence.support.ejb.ejbqlc.Semantic
All Implemented Interfaces:
SemanticTokenTypes
public class Semantic
extends antlr.TreeParser
implements SemanticTokenTypes

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.
