Meta‐function for detecting function types.
Synopsis
Declared in <bslmf_isfunction.h>
template<class t_TYPE>
struct is_function
: bsl::integral_constant<bool, !is_const<const t_TYPE>::value>Description
This struct template implements the is_function meta‐function defined in the C++11 standard [meta.unary.cat]to determine if the (template parameter) t_TYPE is a function type. This struct derives from bsl::true_type if the t_TYPE is a function type, and from bsl::false_type otherwise. This implementation relies on the fact that neither function types nor reference types can be cv‐qualified so that is_const<const t_TYPE> will actually yield false.
