示例1: Deallocate
void FixedAllocator::Deallocate(void *p)
{
assert(last_dealloc_);
assert(!chunks_.empty());
// find the chunk that holds the pointer.
last_dealloc_ = FindChunk(p);
assert(last_dealloc_);
// found the chunk, so forwards deallocation request to it.
last_dealloc_->Deallocate(p, block_size_);
// the chunk is empty, should we free it?
if (last_dealloc_->blocks_available_ == blocks_)
{
MemChunk *last_chunk = &chunks_.back();
if (last_chunk = last_dealloc_)
{
if (chunks_.size() > 1 && last_dealloc_[-1].blocks_available_ == blocks_)
{
// there are two free chunk, so free one.
last_chunk->Free();
chunks_.pop_back();
last_alloc_ = last_dealloc_ = &chunks_.front();
}
}
