Method Detail

value

public char value()

Description copied from interface: CharLit

The literal's value.

Specified by:

value in interface CharLit

value

public CharLit value(char value)

Description copied from interface: CharLit

Set the literal's value.

Specified by:

value in interface CharLit

value

protected <N extends CharLit_c> N value(N n,
                            char value)

typeCheck

public Node typeCheck(TypeChecker tc)
               throws SemanticException

Description copied from interface: NodeOps

Type check the AST. This method is called by the leave() method of the visitor. The method should perform work that should be done after visiting the children of the node. The method may return this or a new copy of the node which will be installed as a child of the node's parent.

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)

Description copied from class: Node_c

Pretty-print the AST using the given CodeWriter.

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.

constantValue

public java.lang.Object constantValue(Lang lang)

Description copied from interface: ExprOps

Return the constant value of the expression, if any. Requires that isConstant() is true.

Specified by:

constantValue in interface ExprOps

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
