Hinweise

BaseChannelObjectWithProperties ist die Basisklasse für BaseChannelWithProperties und BaseChannelSinkWithProperties .BaseChannelObjectWithProperties is the base class for BaseChannelWithProperties and BaseChannelSinkWithProperties.

BaseChannelWithProperties und BaseChannelSinkWithProperties können als Basisklassen für Kanäle und Channelsenken verwendet werden, die benannte Eigenschaften bereitstellen.BaseChannelWithProperties and BaseChannelSinkWithProperties can be used as the base classes for channels and channel sinks that provide named properties.

BaseChannelObjectWithProperties behandelt die komplexe Aufgabe, ein Channelobjekt nach seinen Eigenschaften zu Fragen.BaseChannelObjectWithProperties handles the complex task of asking a channel object for its properties.

Diese Klasse stellt einen Link Aufruf und eine Vererbungs Anforderung auf Klassenebene dar.This class makes a link demand and an inheritance demand at the class level. Eine SecurityException wird ausgelöst, wenn der unmittelbare Aufrufer oder die abgeleitete Klasse nicht über eine Infrastruktur Berechtigung verfügt.A SecurityException is thrown when either the immediate caller or the derived class does not have infrastructure permission. Ausführliche Informationen zu Sicherheitsanforderungen finden Sie unter Link Aufrufe und Vererbungs Anforderungen.For details about security demands, see Link Demands and Inheritance Demands.

Hinweise für Ausführende

Wenn Sie von Erben BaseChannelObjectWithProperties , müssen Sie die Keys -Eigenschaft und die-Eigenschaft überschreiben Item[Object] .When you inherit from BaseChannelObjectWithProperties, you must override the Keys property and the Item[Object] property.
