Static Public Member Functions | |
static bool | isLocked (SynchronizedPtr) throw ( SemaphoreException ) |
isLocked determines if the object is currently locked. | |

Return the current grow by count for the pool. | |
static Short | getTotalCurrentSize (void) |
Return the current guard pool size. | |
static void | lock (SynchronizedPtr) throw ( SemaphoreException ) |
lock is called by a guard when control is needed over a objects resource access. | |
static void | release (SynchronizedPtr) throw ( SemaphoreException ) |
release is called by a guard object during its destruction. | |
static void | setExtentSize (Short aExtentSize) throw ( Assertion ) |

Protected Member Functions | |
bool | isSynchronizedLocked (SynchronizedPtr) throw ( SemaphoreException ) |
isSynchronizedLocked resolves whether Synchronized is in a locked state. | |
void | lockSynchronized (SynchronizedPtr) throw ( SemaphoreException ) |
lockSynchronized manages the associations of objects to the semaphore in the pool in establishing the guard. | |
void | releaseSynchronized (SynchronizedPtr) throw ( SemaphoreException ) |
releaseSynchronized manages the associations of objects to the semaphore in the pool when releasing a guard. | |
void | createPoolGroup (Short numSems, Short initSize=0) |
createPoolGroup creates a semaphore set with the requested number of semaphores in the group and will add the semaphores to theSemaphores with initial count and index set properly | |
void | destroyPoolGroup (Index aGroup) |
destroyPoolGroup validates that all the semaphores in the extent are not being used and then destroys the extent and all the semaphores associated with it. | |
Static Protected Attributes | |

Default constructor.
Short | number of base semaphores to use in pool | |
Short | number of semaphores to increment by when going into extents. If 0, no extents are allowed. |
