Return the object with the given name from the underlying scope,
Return the conversation ID for the current underlying scope, if any.
Template method that determines the actual target scope.
Remove the object with the given
protected int getScope()
public java.lang.String getConversationId()
The exact meaning of the conversation ID depends on the underlying
storage mechanism. In the case of session-scoped objects, the
conversation ID would typically be equal to (or derived from) the
session ID; in the
case of a custom conversation that sits within the overall session,
the specific ID for the current conversation would be appropriate.
Note: This is an optional operation. It is perfectly valid to
null in an implementation of this method if the
underlying storage mechanism has no obvious candidate for such an ID.
nullif there is no conversation ID for the current scope
public java.lang.Object get(java.lang.String name, ObjectFactory<?> objectFactory)
creating itif not found in the underlying storage mechanism.
This is the central operation of a Scope, and the only operation that is absolutely required.
name- the name of the object to retrieve
ObjectFactoryto use to create the scoped object if it is not present in the underlying storage mechanism
public java.lang.Object remove(java.lang.String name)
namefrom the underlying scope.
null if no object was found; otherwise
returns the removed
Note that an implementation should also remove a registered destruction callback for the specified object, if any. It does, however, not need to execute a registered destruction callback in this case, since the object will be destroyed by the caller (if appropriate).
Note: This is an optional operation. Implementations may throw
UnsupportedOperationException if they do not support explicitly
removing an object.
name- the name of the object to remove
nullif no object was present
