This class implements the ManagedAllocator protocol to provide a fast allocator of arbitrarily-sized blocks of memory.
Declared in <bslma_sequentialallocator.h>
class SequentialAllocator
: public ManagedAllocatorBoth the release method and the destructor atomically delete all memory managed by this allocator; the deallocate method, however, has no effect for this class.
