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 sane defaults.- Parameters:
expectedElements
- The expected number of elements guaranteed not to cause buffer expansion (inclusive).loadFactor
- The load factor for internal buffers. Insane load factors (zero, full capacity) are rejected byObjectByteHashMap.verifyLoadFactor(double)
.

ObjectByteIdentityHashMap
public ObjectByteIdentityHashMap(int expectedElements, double loadFactor, HashOrderMixingStrategy orderMixer) 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 byObjectByteHashMap.verifyLoadFactor(double)
.orderMixer
- Hash key order mixing strategy. SeeHashOrderMixing
for predefined implementations. Use constant mixers only if you understand the potential consequences.

Method Details
-
hashKey
Description copied from class:ObjectByteHashMap
Returns a hash code for the given key.The default implementation mixes the hash of the key with
ObjectByteHashMap.keyMixer
to differentiate hash order of keys between hash containers. Helps alleviate problems resulting from linear conflict resolution in open addressing.The output from this function should evenly distribute keys across the entire integer range.
