public VarHandleSegmentAsBytes
withInvokeBehavior()

Implements abstract java.lang.invoke.VarHandle.withInvokeBehavior.

Returns a VarHandle, with access to the same variable(s) as this VarHandle, but whose invocation behavior of access mode methods is adjusted to invoke behavior.

public VarHandleSegmentAsBytes
withInvokeExactBehavior()

Implements abstract java.lang.invoke.VarHandle.withInvokeExactBehavior.

Returns a VarHandle, with access to the same variable(s) as this VarHandle, but whose invocation behavior of access mode methods is adjusted to invoke-exact behavior.

public VarHandleSegmentAsBytes withInvokeBehavior()

Implements abstract java.lang.invoke.VarHandle.withInvokeBehavior.

Doc from java.lang.invoke.VarHandle.withInvokeBehavior.

Returns a VarHandle, with access to the same variable(s) as this VarHandle, but whose invocation behavior of access mode methods is adjusted to invoke behavior.

If this VarHandle already has invoke behavior this VarHandle is returned.

Invoking hasInvokeExactBehavior() on the returned var handle is guaranteed to return false.

Returns:VarHandleSegmentAsBytes

a VarHandle with invoke behavior
