public JavaThread
createJavaThreadWrapper(Address threadAddr)

Routine for instantiating appropriately-typed wrapper for a JavaThread.

public JavaThread

Note

this returns objects of type JavaThread, CompilerThread, JvmtiAgentThread, NotificationThread, MonitorDeflationThread, StringDedupThread, AttachListenerThread and ServiceThread.

Method Detail

createJavaThreadWrapperback to summary
public JavaThread createJavaThreadWrapper(Address threadAddr)

Routine for instantiating appropriately-typed wrapper for a JavaThread. Currently needs to be public for OopUtilities to access it.

getJavaThreadAtback to summary
public JavaThread getJavaThreadAt(int i)

Note

this returns objects of type JavaThread, CompilerThread, JvmtiAgentThread, NotificationThread, MonitorDeflationThread, StringDedupThread, AttachListenerThread and ServiceThread. The latter seven subclasses of the former. Most operations (fetching the top frame, etc.) are only allowed to be performed on a "pure" JavaThread. For this reason, sun.jvm.hotspot.runtime.JavaThread#isJavaThread has been changed from the definition in the VM (which returns true for all of these thread types) to return true for JavaThreads and false for the seven subclasses. FIXME: should reconsider the inheritance hierarchy; see sun.jvm.hotspot.runtime.JavaThread#isJavaThread.
