Method Detail

initialize

void initialize(HotSpotGraalRuntime runtime,
                GraalHotSpotVMConfig config)

Completes the initialization of this registration by recording the HotSpotGraalRuntime the MBean will provide an JMX interface to.

poll

Object poll(boolean sync)

Polls this registration to see if the MBean is registered in a MBean server.

Parameters:

sync - synchronize with other threads that may be processing this registration. This is useful when the caller knows the server is active (e.g., it has a reference to server) and expects this poll to therefore return a non-null value.

Returns:

an ObjectName that can be used to access the MBean or null if the MBean has not been registered with an MBean server (e.g., no JMX client has attached to the VM)
