  • Method Summary

    Modifier and Type
    Method
    Description
    int
    computeHashCode(E object)
    Computes the hashCode of the object as defined by the user.
    boolean
    equals(E object1, E object2)
    Checks two objects for equality.

  • Method Details

    • computeHashCode

      int computeHashCode(E object)
      Computes the hashCode of the object as defined by the user.

    • equals

      boolean equals(E object1, E object2)
      Checks two objects for equality. The equality check can use the objects own equals() method or a custom method defined by the user. It should be consistent with the computeHashCode() method.
