Method Details

dump

public void dump(OutputStream out)

Dumps all the threads' current information, including synchronization, to an output stream.

Parameters:

out - an output stream

dump

public void dump(boolean lockedMonitors,
 boolean lockedSynchronizers,
 OutputStream out)

Dumps all the threads' current information, optionally including synchronization, to an output stream.

Having control over including synchronization info allows using this method (and its wrappers, i.e. ThreadDumpServlet) in environments where getting object monitor and/or ownable synchronizer usage is not supported. It can also speed things up.

See ThreadMXBean.dumpAllThreads(boolean, boolean)

Parameters:

lockedMonitors - dump all locked monitors if true

lockedSynchronizers - dump all locked ownable synchronizers if true

out - an output stream
