Commenti

BaseChannelObjectWithPropertiesè la classe di base BaseChannelWithProperties per BaseChannelSinkWithPropertiese.BaseChannelObjectWithProperties is the base class for BaseChannelWithProperties and BaseChannelSinkWithProperties.

BaseChannelWithPropertiese BaseChannelSinkWithProperties possono essere usati come classi di base per i canali e i sink di canale che forniscono proprietà denominate.BaseChannelWithProperties and BaseChannelSinkWithProperties can be used as the base classes for channels and channel sinks that provide named properties.

BaseChannelObjectWithPropertiesgestisce l'attività complessa di richiesta di un oggetto canale per le relative proprietà.BaseChannelObjectWithProperties handles the complex task of asking a channel object for its properties.

Questa classe esegue una richiesta di collegamento e una richiesta di ereditarietà a livello di classe.This class makes a link demand and an inheritance demand at the class level. Viene SecurityException generata un'eccezione quando il chiamante immediato o la classe derivata non dispone dell'autorizzazione di infrastruttura.A SecurityException is thrown when either the immediate caller or the derived class does not have infrastructure permission. Per informazioni dettagliate sulle richieste di sicurezza, vedere richieste di collegamento e richieste di ereditarietà.For details about security demands, see Link Demands and Inheritance Demands.

Note per gli eredi

Quando si eredita da BaseChannelObjectWithProperties, è necessario eseguire l' Keys override della proprietà Item[Object] e della proprietà.When you inherit from BaseChannelObjectWithProperties, you must override the Keys property and the Item[Object] property.
