Detailed Description

template<class T>
class IT_Reflect::ValueRef< T >

Template implementation of IT_Reflect::Value that holds a reference to a simple type such as Float, Int, Date etc.

As well as Value this class implements AnySimpleType to support get_reflected calls on simple types that are not class objects.

rhs

)

[virtual]

Returns a reference to an AnyType that is a copy of the AnyType parameter.

Derived classes override this method, providing an appropriate implementation. In this base class, this method is not supported; an exception is always thrown.
