Class SqlASTFactory

java.lang.Object

antlr.ASTFactory

org.hibernate.hql.ast.SqlASTFactory

All Implemented Interfaces:

HqlSqlTokenTypes

public class SqlASTFactory
extends antlr.ASTFactory
implements HqlSqlTokenTypes

Custom AST factory the intermediate tree that causes ANTLR to create specialized AST nodes, given the AST node type (from HqlSqlTokenTypes). HqlSqlWalker registers this factory with itself when it is initialized.

Constructor Details

SqlASTFactory

public SqlASTFactory(HqlSqlWalker walker)

Create factory with a specific mapping from token type to Java AST node type. Your subclasses of ASTFactory can override and reuse the map stuff.

Method Details

getASTNodeType

public Class getASTNodeType(int tokenType)

Returns the class for a given token type (a.k.a. AST node type).

Overrides:

getASTNodeType in class antlr.ASTFactory

Parameters:

tokenType - The token type.

Returns:

Class - The AST node class to instantiate.

createUsingCtor

protected antlr.collections.AST createUsingCtor(antlr.Token token,
 String className)

Overrides:

createUsingCtor in class antlr.ASTFactory

create

protected antlr.collections.AST create(Class c)

Actually instantiate the AST node.

Overrides:

create in class antlr.ASTFactory

Parameters:

c - The class to instantiate.

Returns:

The instantiated and initialized node.
