Member Function Documentation

void * mds::base::CSmallObjectAllocator::allocate

(

tSize

NumBytes

)

Allocates memory.

• Uses an internal pool of CFixedAllocator objects.
• Throws std::bad_alloc exception on failure.

void mds::base::CSmallObjectAllocator::deallocate	(	void *	p,
		tSize	NumBytes
	)

Deallocates memory previously allocated with allocate().

• Undefined behavior if you pass any other pointer.

tSize mds::base::CSmallObjectAllocator::getAlignment

(

)

const

Returns number of bytes between allocation boundaries.

tSize mds::base::CSmallObjectAllocator::getMaxObjectSize

(

)

const

Returns maximal allowed object size.

bool mds::base::CSmallObjectAllocator::trimExcessMemory

(

)

Releases empty chunks from memory.
