Type Members

1. class IndexAny[T] extends Index[T]

   An implementation of org.saddle.Index generic in type T for which there is an Ordering[T] and a ST[T] available in the implicit context.

2. trait IndexMaker[I, O] extends AnyRef

   An IndexMaker takes some input of type I and returns an Index whose elements are of type O.

3. trait IndexMakerLowPriority extends AnyRef

4. class IndexTime extends Index[DateTime]

   A compact native int representation of posix times at millisecond resolution which conforms to and extends the interface of Index[DateTime]

5. sealed trait JoinType extends AnyRef

   There are four basic joins which may be performed between two indexed Saddle objects such as org.saddle.Series or org.saddle.Frame.

6. trait Melter[A, B, C] extends AnyRef

   A Melter operates on a Tuple_N and a Tuple_M and produces a Tuple_N+M which is composed of the corresponding tuple elements.

7. trait MelterLowPriority extends MelterLowerPriority

   Next lowest priority melter implicit instances; takes one arbitrary types and a Tuple_N and produces a Tuple_N+1

8. trait MelterLowerPriority extends AnyRef

   Lowest priority melter implicit instance takes two arbitrary types and produces a Tuple2

9. trait ReIndexer[T] extends AnyRef

   We often need to "reindex" one array/vec/series/frame so as to produce a new one.

10. trait Slice[+T] extends AnyRef

    Slice provides a methodology so that when it is applied to an index, it produces an upper and lower integer offset at which to slice.

11. class SliceAll extends Slice[Nothing]

    Represent a slice over the entire index

12. class SliceDefault[T] extends Slice[T]

    Represent a slice from one key to another, inclusive.

13. class SliceFrom[T] extends Slice[T]

    Represent a slice from key to end of index

14. class SliceTo[T] extends Slice[T]

    Represent a slice from zero to a key.

15. trait Splitter[I, OL, OR] extends AnyRef

    A Splitter operates on an input index whose elements have arity N, and yields the following pair of output indexes: the left has elements whose arity is N-1, where each element has the first N-1 constituents of the original tuple; and the right is an index whose elements were those in the Nth position of the original tuple.

16. trait Stacker[I, J, O] extends AnyRef

    A Stacker operates on two input Index instances and produces a new output Index whose entries are drawn from the Cartesian product of the elements of the original indexes, and whose ordering is likewise specified by the original orderings.

17. trait StackerLowPriority extends AnyRef

    Implicit instance of Stacker for two indexes of arbitrary type.
