## 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

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method and 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
