Comentários

BaseChannelObjectWithPropertiesé a classe base para BaseChannelWithProperties e BaseChannelSinkWithProperties.BaseChannelObjectWithProperties is the base class for BaseChannelWithProperties and BaseChannelSinkWithProperties.

BaseChannelWithPropertiese BaseChannelSinkWithProperties podem ser usados como as classes base para canais e coletores de canal que fornecem propriedades nomeadas.BaseChannelWithProperties and BaseChannelSinkWithProperties can be used as the base classes for channels and channel sinks that provide named properties.

BaseChannelObjectWithPropertiesmanipula a tarefa complexa de solicitar um objeto de canal para suas propriedades.BaseChannelObjectWithProperties handles the complex task of asking a channel object for its properties.

Essa classe faz uma demanda de link e uma demanda de herança no nível de classe.This class makes a link demand and an inheritance demand at the class level. Um SecurityException é gerado quando o chamador imediato ou a classe derivada não tem permissão de infraestrutura.A SecurityException is thrown when either the immediate caller or the derived class does not have infrastructure permission. Para obter detalhes sobre as demandas de segurança, consulte demandas de link e demandas de herança.For details about security demands, see Link Demands and Inheritance Demands.
