Detailed Description

template<typename ArgType, typename ResType>
struct CDPL::Util::NullCheckDereferencer< ArgType, ResType >

An unary functor for the dereferenciation of pointers with null pointer checking.

Template Parameters

ArgType	The pointer type.
ResType	The type of the pointer dereferenciation result.

Note

The type resulting from dereferencing ArgType must be convertible to ResType. If ResType is a not a reference, a copy of the pointed-to object will be returned.
