org.apache.commons.collections.map.TypedSortedMap
public class TypedSortedMap
extends java.lang.Object
Decorates another
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.
The returned implementation is Serializable from Commons Collections 3.1.
