Class ConcurrentWriteLockedOffHeapHashMap<K,V>

java.lang.Object
  java.util.AbstractMap<K,V>
      org.terracotta.offheapstore.concurrent.AbstractConcurrentOffHeapMap<K,V>
          org.terracotta.offheapstore.concurrent.ConcurrentWriteLockedOffHeapHashMap<K,V>

Type Parameters:

K - the type of keys maintained by this map

V - the type of mapped values

All Implemented Interfaces:

ConcurrentMap<K,V>, Map<K,V>, ConcurrentMapInternals, HashingMap<K,V>, MapInternals

public class ConcurrentWriteLockedOffHeapHashMap<K,V>
extends AbstractConcurrentOffHeapMap<K,V>

A striped exclusive-read/write map.

This implementation uses instances of WriteLockedOffHeapHashMap for its segments.

Constructor Detail

ConcurrentWriteLockedOffHeapHashMap

public ConcurrentWriteLockedOffHeapHashMap(PageSource tableSource,
                                           Factory<? extends StorageEngine<? super K,? super V>> storageEngineFactory)

Creates a map using the given table buffer source and storage engine factory.

Parameters:

tableSource - buffer source from which hash tables are allocated

storageEngineFactory - factory for the segment storage engines

ConcurrentWriteLockedOffHeapHashMap

public ConcurrentWriteLockedOffHeapHashMap(PageSource tableSource,
                                           Factory<? extends StorageEngine<? super K,? super V>> storageEngineFactory,
                                           long tableSize,
                                           int concurrency)

Creates a map using the given table buffer source, storage engine factory, initial table size, and concurrency.

Parameters:

tableSource - buffer source from which hash tables are allocated

storageEngineFactory - factory for the segment storage engines

tableSize - initial table size (summed across all segments)

concurrency - number of segments
