Detailed Description

This abstract class is the base class for the collection of
attributes of a dynamic object.

Library: dynmvsvr

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.

Member Function Documentation

newAttribute()

virtual IlsDynAttribute* IlsDynAttributes::newAttribute ( IlsDynObject &  , const IlsAttributeDef &    )

virtual

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 IlsDynAttributeFactory::addAttribute().

rmAttribute()

virtual void IlsDynAttributes::rmAttribute ( const IlsAttributeDef &  , IlsBoolean  del = IlsTrue  )

pure virtual

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.
