Class FixedSizeSortedMap
- Map, Serializable, SortedMap, BoundedMap
public class FixedSizeSortedMap
Decorates another
SortedMap
to fix the size blocking add/remove.
Any action that would change the size of the map is disallowed.
The put method is allowed to change the value associated with an existing
key however.
If trying to remove or clear the map, an UnsupportedOperationException is
thrown. If trying to put a new mapping into the map, an
IllegalArgumentException is thrown. This is because the put method can
succeed if the mapping's key already exists in the map, so the put method
is not always unsupported.
This class is Serializable from Commons Collections 3.1.
