Interface LinearTypeOrderBuilder

  • All Known Implementing Classes:
    LinearTypeOrderBuilderImpl

    public interface LinearTypeOrderBuilder
    Defines a pre-order on types. This pre-order is later embedded in a total order an can be used in index comparators.
    • Method Summary

      Modifier and Type Method Description
      void add​(String[] types)
      Add pairs types[i] < types[i+1], for each i < (types.length-1), to the partial sort order.
      LinearTypeOrder getOrder()
      Return a total order of the type names added earlier that is consistent with the pre-order defined through calls to add().
    • Method Detail

      • add

        void add​(String[] types)
          throws CASException
        Add pairs types[i] < types[i+1], for each i < (types.length-1), to the partial sort order. This method can be called as often as desired. It will throw an exception if the pairs could not be successfully added to the relation. A pair can not be added if the resulting relation is no longer a partial order. If you need to know exactly which pair fails, always call add() with a two-element array.
        Parameters:
        types - types to add
        Throws:
        CASException - When adding pairs would make order inconsistent.
      • getOrder

        LinearTypeOrder getOrder()
                          throws CASException
        Return a total order of the type names added earlier that is consistent with the pre-order defined through calls to add().
        Returns:
        An array of Strings in ascending order.
        Throws:
        CASException - if any error
