Thread-safe allocator that manages pooled memory blocks of uniform size.
Declared in <bdlma_concurrentpoolallocator.h>
class ConcurrentPoolAllocator
: public bslma::AllocatorThis class implements the bslma::Allocator protocol to provide an allocator that manages pooled memory blocks of some uniform size, specified either at construction, or at the first invocation of the allocate method. This allocator maintains an internal linked list of free memory blocks, and dispenses one block for each allocate method invocation. When a memory block is deallocated, it is returned to the free list for potential reuse.
This class guarantees thread-safety while allocating or releasing memory.

allocate | Return a newly allocated block of memory of (at least) size bytes. |
blockSize | Return the size (in bytes) of the memory blocks allocated from this allocator. Note that all blocks dispensed by this allocator have the same size. |

do_allocate [virtual] | Return a newly allocated block of at least bytes with alignment. |
do_deallocate [virtual] | Return the memory block at p having bytes and alignment. |
do_is_equal [virtual] | Return whether this allocator can exchange memory with other. |
