Detailed Description

template<typename FunctionObject, typename T, typename Result = void>
class ecl::UnaryFunctionReference< FunctionObject, T, Result >

Creates a unary function from a reference wrapper.

Takes a reference wrapper containing a unary function (strictly by definition) object reference and creates a UnaryFunction descendant. This is useful in utilising the inheritance from UnaryFunction (needed for slots and similar classes).

Template Parameters:

FunctionObject	: type of the function object to be referenced.
Result	: the return type of the unary function.
