Class IntegrationObjectSupport

java.lang.Object

org.springframework.integration.context.IntegrationObjectSupport

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.InitializingBean, org.springframework.context.ApplicationContextAware, NamedComponent

Direct Known Subclasses:

AbstractConnectionFactory, AbstractEndpoint, AbstractMailReceiver, AbstractMessageChannel, AbstractMessageHandler, AbstractRequestHandlerAdvice, AbstractTransformer, ByteStreamReadingMessageSource, CharacterStreamReadingMessageSource, CodecMessageConverter, DefaultHeaderChannelRegistry, DirectMessageReceivingMessageSource, ExpressionEvaluatingTransactionSynchronizationProcessor, FeedEntryMessageSource, FileReadingMessageSource, HeaderEnricher, HeaderFilter, JdbcPollingChannelAdapter, JmsDestinationPollingSource, JpaPollingChannelAdapter, MentionsReceivingMessageSource, MongoDbMessageSource, RedisStoreMessageSource, SearchReceivingMessageSource, StoredProcPollingChannelAdapter, TimelineReceivingMessageSource

public abstract class IntegrationObjectSupport
extends java.lang.Object
implements org.springframework.beans.factory.BeanNameAware, NamedComponent, org.springframework.context.ApplicationContextAware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.InitializingBean

A base class that provides convenient access to the bean factory as well as TaskScheduler and ConversionService instances.

This is intended to be used as a base class for internal framework components whereas code built upon the integration framework should not require tight coupling with the context but rather rely on standard dependency injection.
