Description
Template based implementation of a DynamicAnyHolder. Conversion work happens in the template specializations of this class.
DynamicAny can be used for any type for which a specialization for DynamicAnyHolderImpl is available.
DynamicAnyHolderImpl throws following exceptions: NotImplementedException (if the specialization for a type does not exist) RangeException (if an attempt is made to assign a numeric value outside of the target min/max limits SyntaxException (if an attempt is made to convert a string containing non-numeric characters to number)
All specializations must additionally implement a public member function:
const T& value() const
returning a const reference to the actual stored value.
