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
