Class WorkContext

java.lang.Object

org.fabric3.spi.container.invocation.WorkContext

All Implemented Interfaces:

java.io.Serializable

public class WorkContext
extends java.lang.Object
implements java.io.Serializable

Tracks information associated with a request as it is processed by the runtime. Requests originate at a domain boundary (e.g. a service bound to a transport). WorkContext instances are cached per runtime thread and reused. This implementation is not thread safe.
