org.apache.tuscany.core.context.scope.SessionScopeContext
public class SessionScopeContext
An implementation of an session-scoped component container. This scope contexts eagerly starts contexts when a
SessionStart
event is received. If a contained context has an implementation
marked to eagerly initialized, the an instance will be created at that time as well. Contained contexts are shutdown when a
SessionEnd
event is received in reverse order to which their implementation
instances were created.
TODO this implementation needs to be made generic so that it supports a range of session types, i.e. not tied to HTTP
session scope
