Constructor & Destructor Documentation

AsyncUtility::AsyncUtility (  float  frequency = 0.2  )

Definition at line 47 of file asyncUtility.cxx.

AsyncUtility::~AsyncUtility (  void   )  [virtual]

Definition at line 66 of file asyncUtility.cxx. References _threaded, _threads_enabled, create, and st_callback().

Member Function Documentation

void AsyncUtility::callback (  void   )  [protected]

This is the main body of the sub-thread. It waits forever for a request to show up, and then serves it. Definition at line 160 of file asyncUtility.cxx.

void AsyncUtility::create_thread (  void   )

Definition at line 80 of file asyncUtility.cxx. References _shutdown, and _threaded.

void AsyncUtility::destroy_thread (  void   )  [protected]

Definition at line 99 of file asyncUtility.cxx. Referenced by Loader::Loader().

float AsyncUtility::get_frequency (  void   )  const [inline]

Definition at line 43 of file asyncUtility.I.

void AsyncUtility::nap (  void   )  const [protected]

Definition at line 179 of file asyncUtility.cxx.

virtual bool AsyncUtility::process_request (  void   )  [protected, pure virtual]

Implemented in Loader.

void AsyncUtility::set_frequency (  float  frequency  )  [inline]

Fraction of a second. Definition at line 31 of file asyncUtility.I. References _frequency, and INLINE.

void * AsyncUtility::st_callback (  void *  arg  )  [static, protected]

This is a static wrapper around the callback() method, below. It's static just so we can pass it to the thread-creation function. In addition, the function has a void* return type even though we don't actually return anything. This is necessary because ipc assumes a function that does not return anything indicates that the associated thread should be created as unjoinable (detached).
