|---|---|
water.fvec.C1NChunk |
chunkForChunkIdx(int cidx)
The Chunk for a chunk#.
|
byte[] |
getFirstBytes()
Get an unspecified amount of initial bytes; typically a whole C1NChunk of
length Vec.DFLT_CHUNK_SIZE but no guarantees.
|
boolean |
isInt()
Is all integers? Yes, it's all bytes
|
long |
naCnt()
Return column missing-element-count - ByteVecs do not allow any "missing elements"
|
java.io.InputStream |
openStream() |
java.io.InputStream |
openStream(Key job_key)
Open a stream view over the underlying data
