Description

This abstract class is the base class for the collection of attributes of a dynamic object. It provides the API used by Rogue Wave® Server to create or access dynamic attributes. If you choose to subclass this class, you must use the member function IlsDynObjectFactory::newAttributes to create instances of your subclass.

public:

IlsDynAttributes(IlsDynObject* holder);

Constructor

IlsDynAttributes(IlsDynObject* holder);

This constructor receives the holder object for the collection to be built.

Member Functions

[virtual] IlsDynObject* getHolder() const;

This member function returns the holder of the collection. This function should be overriden.

[virtual] IlsDynAttribute* getDynAttribute

(const IlsDynObject& holder,

const IlsAttributeDef&) const;

This virtual member function returns a dynamic attribute, given its definition and its holder. This function should be overriden.

[virtual] void addAttribute(const IlsAttributeDef&, IlsDynAttribute&);

This virtual member function adds a dynamic attribute to the collection. This function should be overriden.

[virtual] void rmAttribute(const IlsAttributeDef&, IlsBoolean del = IlsTrue);

This virtual member function removes a dynamic attribute from the collection. If the argument del is IlsTrue, the dynamic attribute must be deleted. This function should be overriden.

[virtual] IlsDynAttribute* newAttribute(IlsDynObject&, const IlsAttributeDef&);

This virtual member function is called by Server when a new attribute must be built. The default implementation invokes the methods of the class IlsDynAttributeFactory and calls addAttribute.

[virtual] int getCount() const;

This virtual member function returns the number of dynamic attributes stored in the collection.
