Member Function Documentation

virtual void* xercesc::DOMMemoryManager::allocate (  XMLSize_t  amount, DOMMemoryManager::NodeObjectType  type )  [pure virtual]

Allocate a memory block of the requested size from the managed pool of DOM objects. Parameters: amount  the size of the new memory block type  the type of the DOM object that will be stored in the block Returns: the pointer to the newly allocated block

virtual void* xercesc::DOMMemoryManager::allocate (  XMLSize_t  amount  )  [pure virtual]

Allocate a memory block of the requested size from the managed pool. Parameters: amount  the size of the new memory block Returns: the pointer to the newly allocated block

virtual XMLCh* xercesc::DOMMemoryManager::cloneString (  const XMLCh *  src  )  [pure virtual]

Allocate a memory block from the mnaged pool and copy the provided string. Parameters: src  the string to be copied Returns: the pointer to the newly allocated block

virtual XMLSize_t xercesc::DOMMemoryManager::getMemoryAllocationBlockSize (   )  const [pure virtual]

Returns the size of the chunks of memory allocated by the memory manager. Returns: the dimension of the chunks of memory allocated by the memory manager

virtual void xercesc::DOMMemoryManager::release (  DOMNode *  object, DOMMemoryManager::NodeObjectType  type )  [pure virtual]

Release a DOM object and place its memory back in the pool. Parameters: object  the pointer to the DOM node type  the type of the DOM object

virtual void xercesc::DOMMemoryManager::setMemoryAllocationBlockSize (  XMLSize_t  size  )  [pure virtual]

Set the size of the chunks of memory allocated by the memory manager. Parameters: size  the new size of the chunks; it must be greater than 4KB
