org.apache.camel.support

Class MessageSupport

java.lang.Object

org.apache.camel.support.MessageSupport

All Implemented Interfaces:

org.apache.camel.CamelContextAware, org.apache.camel.Message, org.apache.camel.spi.DataTypeAware

Direct Known Subclasses:

DefaultMessage

public abstract class MessageSupport
extends Object
implements org.apache.camel.Message, org.apache.camel.CamelContextAware, org.apache.camel.spi.DataTypeAware

A base class for implementation inheritance providing the core Message body handling features but letting the derived class deal with headers. Unless a specific provider wishes to do something particularly clever with headers you probably want to just derive from DefaultMessage
