public ASTPrinter(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).

Parameters:

tokenTypeConstants - The class with token type constants in it.

				tokenTypeName = getTokenTypeName( field, type, true );
				if ( tokenTypeName != null ) {
					break;	// Stop if found.
				}

		} // if type constants were provided
		// Use the integer value if no token type name was found
		if ( tokenTypeName == null ) {
			tokenTypeName = Integer.toString( type );
		}
		return tokenTypeName;
}

Get a single token type name in the specified set of token type constants (interface).

 public boolean isShowClassNames() 
{
		return showClassNames;
}

Returns true if the node class names will be displayed.

 public String nodeToString(AST ast,
    boolean showClassName) 
{
		if ( ast == null ) {
			return "{null}";
		}
		StringBuffer buf = new StringBuffer();
		buf.append( "[" ).append( getTokenTypeName( ast.getType() ) ).append( "] " );
		if ( showClassName ) {
			buf.append( StringHelper.unqualify( ast.getClass().getName() ) ).append( ": " );
		}
        buf.append( "'" );
        String text = ast.getText();
        appendEscapedMultibyteChars(text, buf);
        buf.append( "'" );
		if ( ast instanceof DisplayableNode ) {
			DisplayableNode displayableNode = ( DisplayableNode ) ast;
			// Add a space before the display text.
			buf.append( " " ).append( displayableNode.getDisplayText() );
		}
		String s = buf.toString();
		return s;
}

 public  void setShowClassNames(boolean showClassNames) 
{
		this.showClassNames = showClassNames;
}

Enables or disables AST node class name display.

 public String showAsString(AST ast,
    String header) 
{
		ByteArrayOutputStream baos = new ByteArrayOutputStream();
		PrintStream ps = new PrintStream( baos );
		ps.println( header );
		showAst( ast, ps );
		ps.flush();
		return new String( baos.toByteArray() );
}

Prints the AST in 'ASCII art' tree form into a string.

 public  void showAst(AST ast,
    PrintWriter pw) 
{
		ArrayList parents = new ArrayList();
		showAst( parents, pw, ast );
		pw.flush();
}

Prints the AST in 'ASCII art' tree form to the specified print writer.
