public interface TObjectHashingStrategy<T> extends java.io.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- Version:

computeHashCode
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
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
- anObject
valueo2
- anObject
value- Returns:
- true if the objects are equal according to this strategy.
