java.lang.Object oracle.jbo.mom.DefinitionContext
public abstract class DefinitionContext
This abstract class encapsulates the thread-specific behavior and state
needed by the DefinitionManager
class.
The thread-specific behavior and state can be subdivided into two pieces: a MOM (MetaObject Manager) cache and a MOM parser.
The MOM cache maps metaobject names into metaobjects. Subclasses may optionally support ageing out ("retiring") of least-recently-used metaobjects. A retired cache entry typically retains a weak reference to the metaobject.
The MOM parser supports reading and parsing metaobject documents from a store of some sort. (Different subclasses may support different sorts of stores).
Each DefinitionManager
instance will have a set
of associated DefinitionContext
instances,
one per active client thread. In some cases, a single
DefinitionContext
instance can be shared by multiple threads
that are running the same application.
In general, the methods on this class and its subclasses are thread-safe.
