io.debezium.util.HashCode

@Immutable
public class HashCode
extends Object

Utilities for easily computing hash codes. The algorithm should generally produce good distributions for use in hash-based containers or collections, but as expected does always result in repeatable hash codes given the inputs.

Method Detail

compute

public static int compute(Object... objects)

Compute a combined hash code from the supplied objects. This method always returns 0 if no objects are supplied.

Parameters:

objects - the objects that should be used to compute the hash code

Returns:

the hash code

computeHashCode

private static int computeHashCode(int seed,
                                   Object... objects)

Compute a combined hash code from the supplied objects using the supplied seed.

Parameters:

seed - a value upon which the hash code will be based; may be 0

objects - the objects that should be used to compute the hash code

Returns:

the hash code
