ObjectIdentityHashSet
public ObjectIdentityHashSet()New instance with sane defaults. -
ObjectIdentityHashSet
public ObjectIdentityHashSet(int expectedElements) New instance with sane defaults. -
ObjectIdentityHashSet
public ObjectIdentityHashSet(int expectedElements, double loadFactor) New instance with sane defaults. -
ObjectIdentityHashSet
public ObjectIdentityHashSet(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 byObjectHashSet.verifyLoadFactor(double)
.orderMixer
- Hash key order mixing strategy. SeeHashOrderMixing
for predefined implementations. Use constant mixers only if you understand the potential consequences.

hashKey
Description copied from class:ObjectHashSet
Returns a hash code for the given key. The default implementation mixes the hash of the key withObjectHashSet.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.- Overrides:

from
Create a set from a variable number of arguments or an array ofKType
. The elements are copied from the argument to the internal buffer.
