Constructor Detail

AbstractPersistentConcurrentOffHeapCache

public AbstractPersistentConcurrentOffHeapCache(Factory<? extends PinnableSegment<K,V>> segmentFactory)

Create a concurrent map using a default number of segments.

Parameters:

segmentFactory - factory used to create the map segments

AbstractPersistentConcurrentOffHeapCache

public AbstractPersistentConcurrentOffHeapCache(Factory<? extends PinnableSegment<K,V>> segmentFactory,
