Class HashCode

java.lang.Object
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.

    • 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
