Description

Many times, the object model'd code cannot be altered for ocm.

To avoid the "unsupported" exception in almost all such cases, use a delegating wrapper class to encapsulate a Collection. The wrapper class implements MaangeableCollection.

Since delegation is a performance hit, make the test below the last resort for object conversion in the method:
public static ManageableCollection getManageableCollection(Object object)

Proposed "catchall" test and program action:

if (object instanceof Collection)

{ return new ManageableCollectionImpl((Collection)object); }
