| Class | Description |
|---|---|
| AppendableVec |
A NEW single distributed vector column.
|
| ByteVec |
A vector of plain Bytes.
|
| Chunk |
A compression scheme, over a chunk of data - a single array of bytes.
|
| CreateInteractions |
Helper to create interaction features between enum columns
|
| EnumWrappedVec |
A vector transforming values of given vector according to given domain
mapping - currently only used to transform Enum columns but in theory would
work for any dense-packed Int column.
|
| EnumWrappedVec.EnumWrappedChunk | |
| FileVec | |
| Frame |
A collection of named
Vecs, essentially an R-like Distributed Data Frame. |
| Frame.VecSpecifier |
Pair of (column name, Frame key).
|
| FrameCreator |
Helper to make up a Frame from scratch, with random content
|
| HDFSFileVec |
Vec representation of file stored on HDFS.
|
| NewChunk | |
| NFSFileVec |
A NFS distributed file-backed Vector

|
| RebalanceDataSet.RebalanceTask | |
| StrWrappedVec |
A vector transforming values of given vector according to given domain
mapping - currently only used to transform Enum columns but in theory would
work for any dense-packed Int column.
|
| SubsetVec |
A simple wrapper for looking at only a subset of rows
|
| UploadFileVec |
Build a Vec by reading from an InputStream
|
| UploadFileVec.ReadPutStats | |
| Vec |
A distributed vector/array/column of uniform data.
|
| Vec.CollectDomain |
Collect numeric domain of given vector
A map-reduce task to collect up the unique values of an integer vector
and returned as the domain for the vector.
|
| Vec.CollectDomainFast |
(Optimized for positive ints) Collect numeric domain of given vector
A map-reduce task to collect up the unique values of an integer vector
and returned as the domain for the vector.
|
| Vec.VectorGroup |
Class representing the group of vectors.
|
| Vec.Writer |
A more efficient way to write randomly to a Vec - still single-threaded,
still slow, but much faster than Vec.set().
