Class ObjectStoreToMapAdapter<T extends Serializable>

java.lang.Object

org.mule.runtime.core.util.store.ObjectStoreToMapAdapter<T>

Type Parameters:

T - the generic type of the instances contained in the ListableObjectStore

All Implemented Interfaces:

Map<Serializable,T>

Direct Known Subclasses:

LazyObjectStoreToMapAdapter, SimpleObjectStoreToMapAdapter

public abstract class ObjectStoreToMapAdapter<T extends Serializable>
extends Object
implements Map<Serializable,T>

Adapts the object store interface to a map interface so the client doesn't have to deal with all the ObjectStoreExceptions thrown by ObjectStore.

This class provides limited functionality from the Map interface. It does not support some methods (see methods javadoc) that can have a big impact in performance due the underlying object store being used.

The object store provided will be access for completing the map operations but the whole lifecycle of the provided object store must be handled by the user.

Operations of this map are not thread safe so the user must synchronize access to this map properly.
