Constructor Detail

ObjectLongIdentityHashMap

public ObjectLongIdentityHashMap()

New instance with sane defaults.

ObjectLongIdentityHashMap

public ObjectLongIdentityHashMap(int expectedElements)

New instance with sane defaults.

Parameters:

expectedElements - The expected number of elements guaranteed not to cause buffer expansion (inclusive).

ObjectLongIdentityHashMap

public ObjectLongIdentityHashMap(int expectedElements,
                                 double loadFactor)

New instance with the provided defaults.

Parameters:

expectedElements - The expected number of elements guaranteed not to cause a rehash (inclusive).

loadFactor - The load factor for internal buffers. Insane load factors (zero, full capacity) are rejected by ObjectLongHashMap.verifyLoadFactor(double).

ObjectLongIdentityHashMap

public ObjectLongIdentityHashMap(ObjectLongAssociativeContainer<? extends KType> container)

Create a hash map from all key-value pairs of another container.

Method Detail

hashKey

public int hashKey(KType key)

Description copied from class: ObjectLongHashMap

Returns a hash code for the given key.

The output from this function should evenly distribute keys across the entire integer range.

Overrides:

hashKey in class ObjectLongHashMap<KType>

equals

public boolean equals(java.lang.Object v1,
                      java.lang.Object v2)

Overrides:

equals in class ObjectLongHashMap<KType>

from

public static <KType> ObjectLongIdentityHashMap<KType> from(KType[] keys,
                                                            long[] values)
