Detailed Description

The Chunk structure has to be used with great care. A represents is a block of memory, in which it allocates small objects. Be sure that the blockSize used in the calls is the same for all calls to an instance.

Member Function Documentation

◆ allocate()

void * FixedAllocator::Chunk::allocate ( std::size_t  blockSize)

returns 0 if no more blocks are available.

Referenced by FixedAllocator::allocate().

◆ deallocate()

void FixedAllocator::Chunk::deallocate ( void *  p,
std::size_t  blockSize 
)

deallocates the given pointer.

Make sure that p was allocated by the same instance on which you call deallocate.

References p.

Referenced by FixedAllocator::deallocate().

◆ free()

void FixedAllocator::Chunk::free ( )

call this method instead of a destructor

◆ init()

void FixedAllocator::Chunk::init ( std::size_t  blockSize,
unsigned char  numBlocks 
)

be careful. numBlocks has to be <= 255.

References m_firstAvailableBlock, m_numAvailableBlocks, m_pData, and p.
