Class VirtualState

java.lang.Object

org.graalvm.compiler.graph.Node

org.graalvm.compiler.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.
