An STL-compatible test allocator that forwards to a bslma::TestAllocator.
Declared in <bslma_stdtestallocator.h>
template<class TYPE>
class StdTestAllocator;This class template forwards allocation calls to an underlying mechanism object of a type derived from bslma::TestAllocator. It adheres to the allocator requirements defined in section 20.1.5 [lib.allocator.requirements]of the C++ standard and may be used to instantiate any [container]class template that follows the STL allocator protocol. The allocation mechanism is chosen at run-time, giving the programmer run-time control over how a container allocates and frees memory.
