public abstract class AbstractChannelAdapterParser
extends AbstractBeanDefinitionParser

Base parser for Channel Adapters.

Includes logic to determine MessageChannel: if 'channel' attribute is defined - uses its value as 'channelName'; if 'id' attribute is defined - creates DirectChannel at runtime and uses id's value as 'channelName'; if current component is defined as nested element inside any other components e.g. <chain> 'id' and 'channel' attributes will be ignored and this component will not be parsed as AbstractEndpoint.

doParse

protected abstract AbstractBeanDefinition doParse(Element element,
                                                  ParserContext parserContext,
                                                  String channelName)

Subclasses must implement this method to parse the adapter element. The name of the MessageChannel bean is provided.

Parameters:

element - The element.

parserContext - The parser context.

channelName - The channel name.

Returns:

The bean definition.
