Class VirtualState

java.lang.Object

com.oracle.graal.graph.Node

com.oracle.graal.nodes.VirtualState

All Implemented Interfaces:

Cloneable, Formattable

Direct Known Subclasses:

EscapeObjectState, FrameState

public abstract class VirtualState
extends Node

Base class for nodes that contain "virtual" state, like FrameState and VirtualObjectState. Subclasses of this class will be treated in a special way by the scheduler.
