Purpose:

Provide a type trait for pointer semantics.

Classes:

bslmf::HasPointerSemantics

meta-function indicating pointer-like types

See also:

Component bslmf_nestedtraitdeclaration

Description:

This component defines a tag type HasPointerSemantics derived from bsl::true_type to indicate that a type has pointer semantics, and from bsl::false_type otherwise. A type has pointer-like semantics must define (at a minimum) operator* and operator->. All pointer types have pointer semantics; other types must explicitly add this trait, either with the macro BSLMF_NESTED_TRAIT_DECLARATION, or by explicit template specialization.
