Examples of org.apache.axis2.engine.Handler

org.apache.axis2.engine.Handler
A Handler represents a piece of message processing functionality in Axis2. Handlers are combined into chains and phases in order to provide customizable functionality such as security, reliability, etc. Handlers must be multi-thread safe and should keep all their state in Context objects (see the org.apache.axis2.context package).
