public class RequestScopeContext
extends AbstractScopeContext

An implementation of a request-scoped component container. This scope contexts eagerly starts contexts when a RequestStart 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 RequestEnd event is received in reverse order to which their implementation instances were created.

Method Detail

onEvent

public void onEvent(Event event)

start

public void start()

Description copied from interface: Lifecycle

Starts the Lifecycle.

stop

public void stop()

Description copied from interface: Lifecycle

Stops the Lifecycle.

isCacheable

public boolean isCacheable()

Description copied from interface: ScopeContext

Returns whether implementation instances may be held for the duration of an wire

registerFactory

public void registerFactory(ContextFactory<Context> configuration)

Description copied from interface: ScopeContext

Adds a context factory to the scope

getContext

public Context getContext(java.lang.String ctxName)

Description copied from interface: ScopeContext

Returns a context bound to the given name or null if the component does not exist. The returned context is bound to a key determined from the thread context.

getContextByKey

                               java.lang.Object key)

Description copied from interface: ScopeContext

Returns a context bound to the given name and scoped to the given key or null if the context does not exist

removeContext

public void removeContext(java.lang.String ctxName)

Description copied from interface: ScopeContext

Removes a context with the given name, determining the scope key from the thread context

removeContextByKey

public void removeContextByKey(java.lang.String ctxName,
                               java.lang.Object key)

Description copied from interface: ScopeContext

Removes a context bound to the given name and scope key
