Examples of org.exist.util.hashtable.Object2LongHashMap

org.exist.util.hashtable.Object2LongHashMap
A hashtable which maps object keys to long values. Keys are compared by their object equality, i.e. two objects are equal if object1.equals(object2). @author Stephan Körnig @author Wolfgang Meier (wolfgang@exist-db.org)

    private Object2LongHashMap names;
    private BrokerPool pool;


    public CollectionCache(BrokerPool pool, int blockBuffers, double growthThreshold) {
        super(blockBuffers, 2.0, 0.000001, CacheManager.DATA_CACHE);
        this.names = new Object2LongHashMap(blockBuffers);
        this.pool = pool;
        setFileName("collection cache");
    }

            SequencedLongHashMap<Cacheable> newMap = new SequencedLongHashMap<Cacheable>(newSize * 2);
