Class PersistedMap<K,T,PT>

java.lang.Object

java.util.AbstractMap<K,T>

org.helenus.driver.impl.PersistedMap<K,T,PT>

Type Parameters:

K - the type of the keys

T - the decoded type of the values

PT - the persisted type from which we are decoding and to which we are encoding each values

All Implemented Interfaces:

Map<K,T>, PersistedObject<T,PT>

Direct Known Subclasses:

PersistedSortedMap

public class PersistedMap<K,T,PT>
extends AbstractMap<K,T>
implements PersistedObject<T,PT>

The PersistedMap class provides a Map implementation suitable to hold persisted values.
