Member Function Documentation

void OW_NAMESPACE::CppPolledProviderIFC::doCooperativeCancel (   )  [virtual]

This function is available for subclasses to override if they wish to be notified when a cooperative cancel is being invoked on the thread. Note that this function will be invoked in a separate thread. For instance, a thread may use this function to write to a pipe or socket, if Thread::run() is blocked in select(), it can be unblocked and instructed to exit. It is also possible for an individual thread to override the cancellation request, if it knows that cancellation at this time may crash the system or cause a deadlock. To do this, the thread should throw an CancellationDeniedException. Note that threads are usually only cancelled in the event of a system shutdown or restart, so a thread should make a best effort to actually shutdown. Exceptions: CancellationDeniedException  Definition at line 49 of file OW_CppPolledProviderIFC.cpp.

void OW_NAMESPACE::CppPolledProviderIFC::doDefinitiveCancel (   )  [virtual]

See the documentation for doCooperativeCancel(). When definitiveCancel() is called on a thread, first doCooperativeCancel() will be called, and then doDefinitiveCancel() will be called. Exceptions: CancellationDeniedException  Definition at line 54 of file OW_CppPolledProviderIFC.cpp.

virtual Int32 OW_NAMESPACE::CppPolledProviderIFC::getInitialPollingInterval (  const ProviderEnvironmentIFCRef &  env  )  [pure virtual]

Returns: The amount of seconds before the first call to the poll method. If this method returns zero, then the poll method is never called. Implemented in OW_NAMESPACE::LifecycleIndicationPoller, OW_NAMESPACE::SLPProvider, and OW_NAMESPACE::UnloaderProvider.

CppPolledProviderIFC * OW_NAMESPACE::CppPolledProviderIFC::getPolledProvider (   )  [virtual]

Reimplemented from OW_NAMESPACE::CppProviderBaseIFC. Definition at line 60 of file OW_CppPolledProviderIFC.cpp.

virtual Int32 OW_NAMESPACE::CppPolledProviderIFC::poll (  const ProviderEnvironmentIFCRef &  env  )  [pure virtual]

Called by the CIMOM to give this CppPolledProviderIFC to opportunity to export indications if needed. Parameters: lch  A local CIMOM handle the provider can use to export indications if needed. Returns: How many seconds before the next call to the poll method. If this method returns -1 then the last polling interval will be used. If it returns 0 then the poll method will never be called again. Implemented in OW_NAMESPACE::LifecycleIndicationPoller, OW_NAMESPACE::SLPProvider, and OW_NAMESPACE::UnloaderProvider.
