Interface TObjectHashingStrategy
public
interface
TObjectHashingStrategy
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.

public int computeHashCode(Object o)
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
public boolean equals(Object o1, Object 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.
