//@PURPOSE: Provide a trait to mark classes as having pointer semantics.
//
//@DEPRECATED: Use 'bslmf_haspointersemantics' instead.
//
//@CLASSES:
//  bslalg::TypeTraitHasPointerSemantics: has pointer semantics
//
//@SEE_ALSO:
//
//@DESCRIPTION: This component provides a single traits class,
// 'bslalg::TypeTraitHasPointerSemantics', which allows the trait
// 'bslmf::HasPointerSemantics' to be declared using the (deprecated)
// 'BSLALG_DECLARE_NESTED_TRAITS' macro.  See the 'bslmf_haspointersemantics'
// component for details of this trait.
//
///Usage
///-----
// No Usage example is provided since this component is deprecated.

    // providing the above operators does not imply that a type has pointer
    // semantics.  This trait is intended for "wrapper" types that behave as
    // pointers.  Some examples of such types include 'std::auto_ptr', and
    // 'bslma::ManagedPtr'.  This trait is generally used by objects that
    // invoke the wrapped type.
