void JavaThreadTracker::onThreadStart (  )  [private, virtual]

Called in new thread context before thread's body runs.

Reimplemented from ThreadTracker.

Definition at line 30 of file JavaThreadTracker.cpp.

References JniEnvAutoRef::suppressDetach().

00031 {
00032     JniEnvAutoRef pEnv;
00033     // We want to stay attached for the duration of the timer thread,
00034     // so suppress detach here and do it explicitly in onThreadEnd
00035     // instead.  See comments on suppressDetach about the need for a
00036     // cleaner approach to attaching native-spawned threads.
00037     pEnv.suppressDetach();
00038 }

void JavaThreadTracker::onThreadEnd (  )  [private, virtual]

FennelExcn * JavaThreadTracker::cloneExcn ( std::exception &  ex  )  [private, virtual]

Parameters:
ex the excn to be cloned
Returns:
cloned excn
