Class MonitorIdNode

java.lang.Object

org.graalvm.compiler.graph.Node

org.graalvm.compiler.nodes.ValueNode

org.graalvm.compiler.nodes.java.MonitorIdNode

All Implemented Interfaces:

Cloneable, Formattable, IterableNodeType, NodeInterface, LIRLowerable, ValueNodeInterface

public class MonitorIdNode
extends ValueNode
implements IterableNodeType, LIRLowerable

This node describes one locking scope; it ties the monitor enter, monitor exit and the frame states together. It is thus referenced from the MonitorEnterNode, from the MonitorExitNode and from the FrameState.
