Detailed Description

MemoryManager defines a basic interface for a custom memory manager to be uses by ARToolKitPlus.

In various situations it makes sense to have a custom memory manager rather than using the default new/delete functions provided by the c-runtime. To use a custom memory manager it has to be set using ARToolKitPlus::setMemoryManager() before ARToolKitPlus is instantiated. If no memory manager is set, ARToolKitPlus will use the default new/delete functions.

Member Function Documentation

virtual bool ARToolKitPlus::MemoryManager::deinit ( ) [pure virtual]

Releases all memory alloced previously.

After deinit() has been called getMemory() will not be able to reserve memory anymore. deinit( ) releases all memory allocated previously. It is not required to call releaseMemory() after deinit().

virtual bool ARToolKitPlus::MemoryManager::didInit ( ) [pure virtual]

Returns true if the MemoryManager was already initialized.

virtual unsigned int ARToolKitPlus::MemoryManager::getBytesAllocated ( ) [pure virtual]

Returns the number of bytes allocated alltogether.

virtual void* ARToolKitPlus::MemoryManager::getMemory ( size_t  nNumBytes) [pure virtual]

Reserves nNumBytes from previously allocated memory.

init() hast to be called before getMemory can be invoked.

virtual bool ARToolKitPlus::MemoryManager::init ( size_t  nNumInitialBytes,
size_t  nNumGrowBytes = 0 
) [pure virtual]

The MemoryManager will allocate an initial amount of memory.

Each time the MemoryManager does not have enough memory left for a getMemory() request it will allocate another block of nNumGrowBytes bytes.

virtual void ARToolKitPlus::MemoryManager::releaseMemory ( void *  nMemoryBlock) [pure virtual]

Releases a memory block that was allocated via getMemory()
