      • compareStrings

        int compareStrings​(java.lang.String o1,
                           java.lang.String o2)
        Compare two strings
        Parameters:
        o1 - the first string
        o2 - the second string
        Returns:
        0 if the strings are considered equal, a negative integer if the first string is less than the second, a positive integer if the first string is greater than the second
      • comparesEqual

        boolean comparesEqual​(java.lang.String s1,
                              java.lang.String s2)
        Compare two strings for equality. This may be more efficient than using compareStrings and testing whether the result is zero, but it must give the same result
        Parameters:
        s1 - the first string
        s2 - the second string
        Returns:
        true if and only if the strings are considered equal,
      • getCollationKey

        java.lang.Object getCollationKey​(java.lang.String s)
        Get a collation key for a String. The essential property of collation keys is that if (and only if) two strings are equal under the collation, then comparing the collation keys using the equals() method must return true.
        Parameters:
        s - the string whose collation key is required
        Returns:
        the collation key
