Package io.deephaven.util.datastructures

Class SortedIndexableMapWrapper<K,V>

java.lang.Object

io.deephaven.util.datastructures.SortedIndexableMapWrapper<K,V>

All Implemented Interfaces:

io.deephaven.hash.IndexableMap<K,V>, Map<K,V>

public class SortedIndexableMapWrapper<K,V>
extends Object
implements io.deephaven.hash.IndexableMap<K,V>

This is a simple utility class that wraps a map, and presents it as an IndexableMap. The getByIndex() and values() method sort the values according the passed in Comparator. The other access methods (iteration, keySet etc. do not sort the results). Everything that touches the values list should be synchronized.
