Class AccessMonitorNode

java.lang.Object

org.graalvm.compiler.graph.Node

org.graalvm.compiler.nodes.ValueNode

org.graalvm.compiler.nodes.FixedNode

org.graalvm.compiler.nodes.FixedWithNextNode

org.graalvm.compiler.nodes.AbstractStateSplit

org.graalvm.compiler.nodes.memory.AbstractMemoryCheckpoint

org.graalvm.compiler.nodes.java.AccessMonitorNode

All Implemented Interfaces:

Cloneable, Formattable, NodeInterface, DeoptimizingNode, DeoptimizingNode.DeoptAfter, DeoptimizingNode.DeoptBefore, FixedNodeInterface, MemoryKill, SingleMemoryKill, NodeWithState, StateSplit, ValueNodeInterface

Direct Known Subclasses:

MonitorEnterNode, MonitorExitNode

public abstract class AccessMonitorNode
extends AbstractMemoryCheckpoint
implements SingleMemoryKill, DeoptimizingNode.DeoptBefore, DeoptimizingNode.DeoptAfter

The AccessMonitorNode is the base class of both monitor acquisition and release.

The Java bytecode specification allows non-balanced locking. Graal does not handle such cases and throws a BailoutException instead during graph building.
