Interface TObjectHashingStrategy<T>

All Superinterfaces:
Serializable

public interface TObjectHashingStrategy<T>
extends Serializable

Interface to support pluggable hashing strategies in maps and sets. Implementors can use this interface to make the trove hashing algorithms use object values, values provided by the java runtime, or a custom strategy when computing hashcodes. Created: Sat Aug 17 10:52:32 2002

Method Summary

int
computeHashCode(T object)
Computes a hash code for the specified object.
boolean
equals(T o1, T o2)
Compares o1 and o2 for equality.

Method Details

computeHashCode

public int computeHashCode(T object)
Computes a hash code for the specified object. Implementors can use the object's own hashCode method, the Java runtime's identityHashCode, or a custom scheme.
Parameters:
object - for which the hashcode is to be computed
Returns:
the hashCode

equals

public boolean equals(T o1,
                      T o2)
Compares o1 and o2 for equality. Strategy implementors may use the objects' own equals() methods, compare object references, or implement some custom scheme.
Parameters:
o1 - an Object value
o2 - an Object value
Returns:
true if the objects are equal according to this strategy.
