      • areEqual

        boolean areEqual()
        Returns true if there are no differences between the two maps; that is, if the maps are equal.

      • entriesOnlyOnLeft

        <K,​V> entriesOnlyOnLeft()
        Returns an unmodifiable map containing the entries from the left map whose keys are not present in the right map.

      • entriesOnlyOnRight

        <K,​V> entriesOnlyOnRight()
        Returns an unmodifiable map containing the entries from the right map whose keys are not present in the left map.

      • entriesInCommon

        <K,​V> entriesInCommon()

      • equals

        boolean   object)
        Compares the specified object with this instance for equality. Returns true if the given object is also a MapDifference and the values returned by the entriesOnlyOnLeft(), entriesOnlyOnRight(), entriesInCommon() and entriesDiffering() of the two instances are equal.
        Overrides:
         in class 
        Parameters:
        object - the reference object with which to compare.
        Returns:
        true if this object is the same as the obj argument; false otherwise.

        Returns the hash code for this instance. This is defined as the hash code of 
        
 Arrays.asList(entriesOnlyOnLeft(), entriesOnlyOnRight(),
     entriesInCommon(), entriesDiffering())
        Overrides:
         in class
