Field Detail

label

public final Label label
The label which this NAME refers to.

Constructor Detail

NAME

public NAME(TreeFactory tf,
            HCodeElement source,
            Label label)
Constructor.

Method Detail

kind

public int kind()
Description copied from class: Tree
Return an integer enumeration of the kind of this Tree. The enumerated values are defined in TreeKind.

Specified by:
kind in class Tree

build

public Exp build(TreeFactory tf,
                 ExpList kids)
Specified by:
build in class Exp

accept

public void accept(TreeVisitor v)
Accept a visitor

Specified by:
accept in class Tree

rename

public Tree rename(TreeFactory tf,
                   TempMap tm,
                   Tree.CloneCallback cb)
Description copied from class: Tree
Rename while cloning a subtree. This node and all child nodes are cloned; the 'temp' information of all TEMP nodes are renamed according to the supplied TempMap. Note that Temps not belonging to this.getFactory().tempFactory() are not affected. The callback() method of the supplied CloneCallback is invoked once on each subtree cloned, starting from the leaves and working back to the root in a post-order depth-first manner.

Specified by:
rename in class Tree

type

public int type()
Description copied from class: Exp
Result type.

Specified by:
type in interface Typed
Specified by:
type in class Exp
Returns:
Type.POINTER

toString

public String toString()
Overrides:
toString in class Object
