Detailed Description

This class implements a lightweight Mutex by making direct calls to the underlying implementation layer.

It doesn't perform any debugging operations.

Member Function Documentation

void LightMutexDirect::acquire ( ) const [inline]

Grabs the lightMutex if it is available.

If it is not available, blocks until it becomes available, then grabs it. In either case, the function does not return until the lightMutex is held; you should then call unlock().

This method is considered const so that you can lock and unlock const lightMutexes, mainly to allow thread-safe access to otherwise const data.

Also see LightMutexHolder.

void LightMutexDirect::clear_name ( ) [inline]

The lightMutex name is only defined when compiling in DEBUG_THREADS mode.

Definition at line 123 of file lightMutexDirect.I.

bool LightMutexDirect::debug_is_locked ( ) const [inline]
string LightMutexDirect::get_name ( ) const [inline]

The lightMutex name is only defined when compiling in DEBUG_THREADS mode.

Definition at line 144 of file lightMutexDirect.I.

bool LightMutexDirect::has_name ( ) const [inline]

The lightMutex name is only defined when compiling in DEBUG_THREADS mode.

Definition at line 133 of file lightMutexDirect.I.

void LightMutexDirect::output ( ostream &  out) const

This method is declared virtual in LightMutexDebug, but non-virtual in LightMutexDirect.

Definition at line 26 of file lightMutexDirect.cxx.

void LightMutexDirect::release ( ) const [inline]

Releases the lightMutex.

It is an error to call this if the lightMutex was not already locked.

This method is considered const so that you can lock and unlock const lightMutexes, mainly to allow thread-safe access to otherwise const data.

void LightMutexDirect::set_name ( const string &  name) [inline]

The lightMutex name is only defined when compiling in DEBUG_THREADS mode.
