FBB::TypeTrait(3bobcat)
NAME
FBB::TypeTrait - shortdesc
SYNOPSIS
#include <bobcat/typetrait>
DESCRIPTION
FBB::TypeTrait is a traits class. It does not define any member functions or data members, but only types. It can be used to determine the
basic type and other characteristics of (const) plain, (const) pointer
or (const) reference types. It is used, e.g., by the FBB::FnWrap* family of template classes and was designed after Alexandrescu's (2001)
TypeTraits template class.
NAMESPACE
FBB
All constructors, members, operators and manipulators, mentioned in
this man-page, are defined in the namespace FBB.
INHERITS FROM
TYPE
- o Plain: the plain type of any const or non-const plain, pointer,
- lvalue- or rvalue-reference type.
BOOL VALUES
- o isPointer: true if the template type argument represents a
- pointer type, false otherwise.
- o isConst: true if the template type argument represents a const
- type, false otherwise.
- o isRef: true if the template type argument represents an lvalue
- reference type, false otherwise.
- o isR_Ref: true if the template type argument represents a rvalue
- reference type, false otherwise.
EXAMPLE
- The following example shows a fragment of the code used in the
FBB::FnWrap1 class determining the basic type of its Type template
parameter:
- #include <bobcat/typetrait>
...
template <typename Type, typename ReturnType = void>
class FnWrap1
{...
public:typedef typename TypeTrait<Type>::Plain argument_type;... - };
- The above code could have used TypeTrait<Type>::isPointer to determine whether Type actually represents a pointer type.
