The lightMutex name is only defined when compiling in DEBUG_THREADS mode. | |
bool | has_name () const |
The lightMutex name is only defined when compiling in DEBUG_THREADS mode. | |
void | output (ostream &out) const |
This method is declared virtual in LightMutexDebug, but non-virtual in LightMutexDirect. | |
void | release () const |
Releases the lightMutex. | |
void | set_name (const string &name) |
The lightMutex name is only defined when compiling in DEBUG_THREADS mode. |
This class implements a lightweight Mutex by making direct calls to the underlying implementation layer.
It doesn't perform any debugging operations.

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] |
Returns true if the current thread has locked the LightMutex, false otherwise.
This method is only intended for use in debugging, hence the method name; in the LightMutexDirect case, it always returns true, since there's not a reliable way to determine this otherwise.

void LightMutexDirect::output | ( | ostream & | out | ) | const |
This method is declared virtual in LightMutexDebug, but non-virtual in LightMutexDirect.

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.
