public interface Session extends Serializable
An object that encapsulates all conversational state between a UIMAResource
and a particular client. In a local deployment, there will probably be only one session. Distributed deployments often have multiple sessions. If multiple sessions are in use, it is the application's or service wrapper's responsibility to make sure that a Resource'sSession
object is properly set up prior to invoking any of that Resource's methods.Note that a particular component, such as an annotator, may get a handle to a Session object that actually represents a particular namespace within a larger Session. This allows each component to use arbitrary keys for storing information in the session without risking name collisions.
