All Implemented Interfaces:

HCodeElement

public class NATIVECALL
extends INVOCATION

NATIVECALL objects are statements which stand for function calls using standard C calling convention. These are typically used to implement parts of the runtime system (for example, to invoke the garbage collector) and not for java native method calls (which must use the standard java method calling convention).

NATIVECALL

public NATIVECALL(TreeFactory tf,
                  HCodeElement source,
                  TEMP retval,
                  Exp func,

Constructor.

Method Detail

isNative

public boolean isNative()

Specified by:

isNative in class INVOCATION

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 Stm build(TreeFactory tf,
                 ExpList kids)

Specified by:

build in class Stm

accept

public void accept(TreeVisitor v)

Accept a visitor

Specified by:

accept in class INVOCATION

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

toString

public String toString()

Overrides:

toString in class Object
