SqlASTFactory	back to summary
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 Detail

create	back to summary
protected AST create(Class<T> c) Overrides antlr.ASTFactory.create. Actually instantiate the AST node. Parameters c:Class<T> The class to instantiate. Returns:AST The instantiated and initialized node.

create

back to summary

protected AST create(Class<T> c)

Overrides antlr.ASTFactory.create.

Actually instantiate the AST node.

Parameters

c:Class<T>: The class to instantiate.

Returns:AST

The instantiated and initialized node.

createUsingCtor	back to summary
protected AST createUsingCtor(Token token, String className) Overrides antlr.ASTFactory.createUsingCtor.

getASTNodeType	back to summary
public Class<T> getASTNodeType(int tokenType) Overrides antlr.ASTFactory.getASTNodeType. Returns the class for a given token type (a.k.a. AST node type). Parameters tokenType:int The token type. Returns:Class<T> Class - The AST node class to instantiate.

getASTNodeType

back to summary

public Class<T> getASTNodeType(int tokenType)

Overrides antlr.ASTFactory.getASTNodeType.

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

Parameters

tokenType:int: The token type.

Returns:Class<T>
