Constructor Details

ObjectByteIdentityHashMap

public ObjectByteIdentityHashMap()

New instance with sane defaults.

ObjectByteIdentityHashMap

public ObjectByteIdentityHashMap(int expectedElements)

New instance with sane defaults.

Parameters:

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

ObjectByteIdentityHashMap

public ObjectByteIdentityHashMap(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 ObjectByteHashMap.verifyLoadFactor(double).

ObjectByteIdentityHashMap

public ObjectByteIdentityHashMap(ObjectByteAssociativeContainer<? extends KType> container)

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

Method Details

hashKey

public int hashKey(KType key)

Description copied from class: ObjectByteHashMap

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 ObjectByteHashMap<KType>

equals

public boolean equals(Object v1,
 Object v2)

Overrides:

equals in class ObjectByteHashMap<KType>

from

public static <KType>
ObjectByteIdentityHashMap<KType> from(KType[] keys,
 byte[] values)
