| void * | malloc (size_t nbytes=sizeof(T)) |
| Get a chunk of memory from free list cache. More... | |

| 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... | |

This class enables caching of dynamically allocated, fixed-sized classes. Notice that the sizeof (TYPE) 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 sizeof T, and is otherwise ignored since <malloc> always returns a pointer to an item of sizeof (T). Reimplemented from ACE_New_Allocator. |
