Class AccessMonitorNode

java.lang.Object

com.oracle.graal.graph.Node

com.oracle.graal.nodes.ValueNode

com.oracle.graal.nodes.FixedNode

com.oracle.graal.nodes.java.AccessMonitorNode

All Implemented Interfaces:

NodeInterface, DeoptimizingNode, DeoptimizingNode.DeoptAfter, DeoptimizingNode.DeoptBefore, MemoryCheckpoint, MemoryNode, NodeWithState, StateSplit, Cloneable, Formattable, KindProvider

Direct Known Subclasses:

MonitorEnterNode, MonitorExitNode, RawMonitorEnterNode

public abstract class AccessMonitorNode
extends AbstractMemoryCheckpoint
implements MemoryCheckpoint, 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.
