UploadFileVec

protected UploadFileVec(Key key)

Method Detail

writable

public boolean writable()

Description copied from class: Vec

Default read/write behavior for Vecs. AppendableVecs are write-only.

Overrides:

writable in class FileVec

addAndCloseChunk

public void addAndCloseChunk(Chunk c,
                             Futures fs)

close

public void close(water.fvec.C1NChunk c,
                  int cidx,
                  Futures fs)

chunkIdx

public Value chunkIdx(int cidx)

Description copied from class: Vec

Get a Chunk's Value by index. Basically the index-to-key map, plus the DKV.get(). Warning: this pulls the data locally; using this call on every Chunk index on the same node will probably trigger an OOM!

Overrides:

chunkIdx in class FileVec

readPut

public static Key readPut(java.lang.String keyname,
                          java.io.InputStream is,
                          UploadFileVec.ReadPutStats stats)
                   throws java.io.IOException

Throws:

java.io.IOException

readPut

public static Key readPut(Key k,
                          java.io.InputStream is,
                          UploadFileVec.ReadPutStats stats)
                   throws java.io.IOException

Throws:

java.io.IOException

setChunkSize

public int setChunkSize(Frame fr,
                        int chunkSize)

Overrides:

setChunkSize in class FileVec
