Interface DiffableUtils.ValueSerializer<K,V>
-
- Type Parameters:
K
- key type of mapV
- value type of map
- All Known Implementing Classes:
DiffableUtils.DiffableValueReader
,DiffableUtils.DiffableValueSerializer
,DiffableUtils.NonDiffableValueSerializer
,DiffableUtils.StringSetValueSerializer
,NamedDiffableValueSerializer
- Enclosing class:
- DiffableUtils
public static interface DiffableUtils.ValueSerializer<K,V>
Provides read and write operations to serialize map values. Reading of values can be made dependent on map key. Also provides operations to distinguish whether map values are diffable. Should not be directly implemented, instead implement eitherDiffableUtils.DiffableValueSerializer
orDiffableUtils.NonDiffableValueSerializer
.
