BloombergLP::bslma::AAModelIsSupported<TYPE, AAModelLegacy>

Synopsis

Declared in <bslma_aamodel.h>

template<class TYPE>
struct AAModelIsSupported<TYPE, AAModelLegacy>
    : bsl::integral_constant<bool, UsesBslmaAllocator<TYPE>::value || AAModelIsSupported<TYPE, AAModelBsl>::value>

Description

Specialization of AAModelIsSupported for MODEL == AAModelLegacy, yielding true_type if TYPE can use bslma::Allocator * as its memory resource. Specifically, it is true if UsesBslmaAllocator<TYPE> is true or if TYPE::allocator_type exists and is convertible from bslma::Allocator *.
