Constructor Detail

FastNotifyNode

public FastNotifyNode(ValueNode object,
                      boolean notifyAll,
                      int bci)

Method Detail

isNotifyAll

public boolean isNotifyAll()

getKilledLocationIdentity

public org.graalvm.word.LocationIdentity getKilledLocationIdentity()

Description copied from interface: SingleMemoryKill

This method is used to determine which memory location is killed by this node. Returning the special value LocationIdentity.any() will kill all memory locations.

Specified by:

getKilledLocationIdentity in interface SingleMemoryKill

Returns:

the identity of the location killed by this node.

stateDuring

public FrameState stateDuring()

Specified by:

stateDuring in interface DeoptimizingNode.DeoptDuring

setStateDuring

public void setStateDuring(FrameState stateDuring)

Description copied from interface: DeoptimizingNode.DeoptDuring

Sets the FrameState describing the program state during the execution of this node.

Specified by:

setStateDuring in interface DeoptimizingNode.DeoptDuring

computeStateDuring

public void computeStateDuring(FrameState currentStateAfter)

Description copied from interface: DeoptimizingNode.DeoptDuring

Compute the FrameState describing the program state during the execution of this node from an input FrameState describing the program state after finishing the execution of this node.

Specified by:

computeStateDuring in interface DeoptimizingNode.DeoptDuring

canDeoptimize

public boolean canDeoptimize()

Description copied from interface: DeoptimizingNode

Determines if this node needs deoptimization information.

Specified by:

canDeoptimize in interface DeoptimizingNode

getBci

public int getBci()
