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.util.List	acceptCFG(CFGBuilder v, java.util.List succs) Visit this term in evaluation order.
java.lang.Object	constantValue() Returns the constant value of the expression, if any.
Node	copy(NodeFactory nf) Produce a copy of this node using the given NodeFactory.
Term	firstChild() Return the first direct subterm performed when evaluating this term.
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.

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.

firstChild

public Term firstChild()

Description copied from interface: Term

Return the first direct subterm performed when evaluating this term. If this term has no subterms, this should return null. This method is similar to the deprecated entry(), but it should *not* recursively drill down to the innermost subterm. The direct child visited first in this term's dataflow should be returned.

Specified by:

firstChild in interface Term

Overrides:

firstChild in class Lit_c

acceptCFG

public java.util.List acceptCFG(CFGBuilder v,
                                java.util.List succs)

Description copied from class: Term_c

Visit this term in evaluation order.

Specified by:

acceptCFG in interface Term

Overrides:

acceptCFG in class Lit_c

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

copy

public Node copy(NodeFactory nf)

Description copied from interface: NodeOps

Produce a copy of this node using the given NodeFactory.

Specified by:

copy in interface NodeOps

Overrides:

copy in class Node_c
