public class ClassLit_c
extends Lit_c
implements ClassLit

A ClassLit represents a class literal expression. A class literal expressions is an expression consisting of the name of a class, interface, array, or primitive type followed by a period (.) and the token class.

Method Summary
 java.lang.Object constantValue()
          Returns the constant value of the expression, if any.
 boolean isConstant()
          According to the JLS 2nd Ed, sec 15.28, a class literal is not a compile time constant.
 java.lang.Object objValue()
          Cannot return the correct object (except for maybe some of the primitive arrays), so we just return null here.
 void prettyPrint(CodeWriter w, PrettyPrinter tr)
          Write the expression to an output file.

Field Detail

typeNode

protected TypeNode typeNode
Constructor Detail

ClassLit_c

public ClassLit_c(Position pos,
                  TypeNode typeNode)
Method Detail

typeNode

public TypeNode typeNode()
Specified by:
typeNode in interface ClassLit

typeNode

public ClassLit typeNode(TypeNode typeNode)

objValue

public java.lang.Object objValue()
Cannot return the correct object (except for maybe some of the primitive arrays), so we just return null here.


visitChildren

public Node visitChildren(NodeVisitor v)
Description copied from interface: NodeOps
Visit the children of the node.

Specified by:
visitChildren in interface NodeOps
Overrides:
visitChildren in class Node_c
Parameters:
v - The visitor that will traverse/rewrite the AST.
Returns:
A new AST if a change was made, or this.

typeCheck

public Node typeCheck(TypeChecker tc)
               throws SemanticException
Type check the expression.

Specified by:
typeCheck in interface NodeOps
Overrides:
typeCheck in class Node_c
Parameters:
tc - The type checking visitor.
Throws:
SemanticException

toString

public java.lang.String toString()
Overrides:
toString in class Node_c

prettyPrint

public void prettyPrint(CodeWriter w,
                        PrettyPrinter tr)
Write the expression to an output file.

Specified by:
prettyPrint in interface NodeOps
Overrides:
prettyPrint in class Node_c
Parameters:
w - The code writer to which to write.
tr - The pretty printer. This is not a visitor.

isConstant

public boolean isConstant()
According to the JLS 2nd Ed, sec 15.28, a class literal is not a compile time constant.

Specified by:
isConstant in interface Expr
Overrides:
isConstant in class Lit_c

constantValue

public java.lang.Object constantValue()
Description copied from interface: Expr
Returns the constant value of the expression, if any.

Specified by:
constantValue in interface Expr
Specified by:
constantValue in class Lit_c
