Interface HashingStrategy<T>

  • All Superinterfaces:
    java.io.Serializable
    All Known Implementing Classes:
    IdentityHashingStrategy

    public interface HashingStrategy<T>
    extends java.io.Serializable
    Interface to support pluggable hashing strategies in maps and sets. Implementers 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.
    • Method Detail

      • computeHashCode

        int computeHashCode​(T object)
        Computes a hash code for the specified object. Implementers 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 implementers 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.
