Detailed Description

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

Creates a nullary function from a reference wrapper.

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

Template Parameters

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