org.hibernate.hql.ast
Class ASTPrinter  

java.lang.Object
  org.hibernate.hql.ast.ASTPrinter

---

public class ASTPrinter

extends java.lang.Object

An 'ASCII art' AST printer for debugging ANTLR grammars.

---

Field Summary
private  boolean	showClassNames
private  java.lang.Class	tokenTypeConstants
private  java.util.Map	tokenTypeNamesByTokenType

 

Constructor Summary

ASTPrinter(java.lang.Class tokenTypeConstants)           Constructs an org.hibernate.hql.antlr.ASTPrinter, given the class that contains the token type constants (typically the '{grammar}TokenTypes' interface generated by ANTLR).

 

Method Summary
static java.lang.String	getConstantName(java.lang.Class tokenTypeConstants, int type)           Get a single token type name in the specified set of token type constants (interface).
private static java.lang.String	getTokenTypeName(java.lang.reflect.Field field, int type, boolean checkType)
private  java.lang.String	getTokenTypeName(int type)           Returns the token type name for the given token type.
boolean	isShowClassNames()           Returns true if the node class names will be displayed.
java.lang.String	nodeToString(antlr.collections.AST ast, boolean showClassName)
void	setShowClassNames(boolean showClassNames)           Enables or disables AST node class name display.
java.lang.String	showAsString(antlr.collections.AST ast, java.lang.String header)           Prints the AST in 'ASCII art' tree form into a string.
private  void	showAst(java.util.ArrayList parents, java.io.PrintWriter pw, antlr.collections.AST ast)
private  void	showAst(antlr.collections.AST ast, java.io.PrintStream out)           Prints the AST in 'ASCII art' tree form to the specified print stream.
void	showAst(antlr.collections.AST ast, java.io.PrintWriter pw)           Prints the AST in 'ASCII art' tree form to the specified print writer.
private  void	showNode(java.io.PrintWriter pw, antlr.collections.AST ast)
