public interface HasHash<T>

Trait for expressions that has a hash algorithm implemented for the type that it results in.

Since:

3.1.0

Author:

Emil Forslund

Method Summary

Modifier and Type	Method	Description
long	hash(T object)	Hash the specified object into a 64-bit hash.

Method Detail

hash

long hash(T object)

Hash the specified object into a 64-bit hash. If two equal objects are hashed, they must always result in the same hash. However, objects that are not equal may also result in the same hash.

Parameters:

object - the object to hash

Returns:

the 64-bit hashcode
