Class MutableOffsetMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

org.opendaylight.yangtools.util.MutableOffsetMap<K,V>

Type Parameters:

K - the type of keys maintained by this map

V - the type of mapped values

All Implemented Interfaces:

Cloneable, Map<K,V>, Mutable, MutationBehaviour<Mutable>, ModifiableMapPhase<K,V>

@Beta
public abstract class MutableOffsetMap<K,V>
extends AbstractMap<K,V>
implements Cloneable, ModifiableMapPhase<K,V>

A mutable version of ImmutableOffsetMap. It inherits the set of mappings from the immutable version and allows updating/removing existing mappings. New mappings are stored in a dedicated LinkedHashMap to preserve insertion order. It also tracks the need to duplicate the backing array, so the sequence of ImmutableOffsetMap<K, V> source; ImmutableOffsetMap<K, V> result = source.createMutableClone().immutableCopy(); results in source and result sharing the backing objects.

This map does not support null keys nor values.
