IdentityHashingStrategy

public IdentityHashingStrategy()

Method Detail

computeHashCode

public int computeHashCode(K object)

Description copied from interface: HashingStrategy

Computes a hash code for the specified object. Implementers can use the object's own hashCode method, the Java runtime's identityHashCode, or a custom scheme.

Specified by:

computeHashCode in interface HashingStrategy<K>

Parameters:

object - for which the hashcode is to be computed

Returns:

the hashCode

equals

public boolean equals(K o1,
                      K o2)

Description copied from interface: HashingStrategy

Compares o1 and o2 for equality. Strategy implementers may use the objects' own equals() methods, compare object references, or implement some custom scheme.

Specified by:

equals in interface HashingStrategy<K>

Parameters:

o1 - an Object value

o2 - an Object value

Returns:

true if the objects are equal according to this strategy.
