Public Methods | |
ACE_Dynamic_Cached_Allocator (size_t n_chunks, size_t chunk_size) | |
Create a cached memory pool with <n_chunks> chunks each with <chunk_size> size. More... | |
~ACE_Dynamic_Cached_Allocator (void) | |
Clear things up. More... | |
void * | malloc (size_t nbytes=0) |
Get a chunk of memory from free list cache. More... | |
virtual void * | calloc (size_t nbytes, char initial_value='\0') |
Get a chunk of memory from free list cache, giving them <initial_value>. More... | |
virtual void * | calloc (size_t n_elem, size_t elem_size, char initial_value='\0') |
This method is a no-op and just returns 0 since the free list only works with fixed sized entities. More... | |
void | free (void *) |
Return a chunk of memory back to free list cache. More... | |
Private Attributes | |
char * | pool_ |
Remember how we allocate the memory in the first place so we can clear things up later. More... | |
ACE_Locked_Free_List< ACE_Cached_Mem_Pool_Node< char >, ACE_LOCK > | free_list_ |
Maintain a cached memory free list. We use <char> as template parameter, although sizeof(char) is usually less than sizeof(void*). Really important is that <chunk_size> must be >= sizeof(void*). More... | |
size_t | chunk_size_ |
Remember the size of our chunks. More... |
This class enables caching of dynamically allocated, chunks with size <chunk_size>. Notice that the chunk_size
must be greater than or equal to sizeof (void*)
for this to work properly.

Get a chunk of memory from free list cache, giving them <initial_value>. Note that <nbytes> is only checked to make sure that it's <= to <chunk_size>, and is otherwise ignored since <malloc> always returns a pointer to an item of <chunk_size>. Reimplemented from ACE_New_Allocator. |
