  • Method Details

    • getColumns

      Comparable<?>[] getColumns()
      Gets an array of all column values.

    • toString

      String toString()
      Based on the column values (column1,column2,...)
      Overrides:
      toString in class Object

    • equals

      boolean equals(Object obj)
      The equals is based on equal column values.
      Overrides:
      equals in class Object

    • hashCode

      int hashCode()
      The hashCode is based on the column values.
      Overrides:
      hashCode in class Object

    • compareTo

      int compareTo(T o)
      The default ordering is based on column value comparisons. If both values are Strings, will use the model comparator.

      If one tuple has few columns than the other, and all the values are equal, the tuple with fewer columns is considered to be first.
