Detailed Description

template<class T>
class IT_Bus::NillableValue< T >

Nillable template implementation that keeps the data object in a member variable.

Note: This template can only be used for generated types that have a working copy constructor and assignment operator. it cannot be used for primitive and builtin-types

See the header file for complete method details.

const throw ((IT_Reflect::ReflectException)) [virtual]

Return an instance of the IT_Reflect::Reflection type that encapsulates this instance.

Returns:

IT_Reflect::Reflection

template<class T>

AnyType & IT_Bus::NillableValue< T >::copy

(

const AnyType &

other

)

[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.

Parameters:

AnyType

to be copied.

Returns:

A reference to AnyType.

Exceptions:

IT_Bus::Exception

with message "Copy not supported"

Reimplemented from IT_Bus::NillableValueBase< T >.

Definition at line 135 of file nillable_value.h.

template<class T>

const QName & IT_Bus::NillableValue< T >::get_type

(

)

const [virtual]

Returns the IT_Bus::QName for the type.

Derived subclasses implement this method and return their QName.

Returns:

IT_Bus::QName.

Reimplemented from IT_Bus::NillableValueBase< T >.
