Specified by:

kind in interface FloatLit

kind

public FloatLit kind(FloatLit.Kind kind)

Description copied from interface: FloatLit

Set the kind of literal: FLOAT or DOUBLE.

Specified by:

kind in interface FloatLit

kind

protected <N extends FloatLit_c> N kind(N n,
                            FloatLit.Kind kind)

value

public double value()

Description copied from interface: FloatLit

value in interface FloatLit

value

protected <N extends FloatLit_c> N value(N n,
                             double 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

precedence

public Precedence precedence()

Description copied from interface: Expr

Get the precedence of the expression.

Specified by:

precedence in interface Expr

Overrides:

precedence 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
