public class TypedSortedMap extends Object
SortedMap to validate that elements added
are of a specific type.
The validation of additions is performed via an instanceof test against
a specified Class. If an object cannot be added to the
collection, an IllegalArgumentException is thrown.
Note that TypedSortedMap is not synchronized and is not thread-safe.
If you wish to use this map from multiple threads concurrently, you must use
appropriate synchronization. The simplest approach is to wrap this map
using Collections.synchronizedSortedMap(java.util.SortedMap). This class may throw
exceptions when accessed by concurrent threads without synchronization.
The returned implementation is Serializable from Commons Collections 3.1.
