int chunkIdx) |
| Modifier and Type | Method and Description |
|---|---|
Chunk |
chunkForChunkIdx(int cidx)
Map from chunk-index to Chunk.
|
int |
chunkLen(int cidx)
Number of rows in chunk.
|
int |
elem2ChunkIdx(long i)
Convert a row# to a chunk#.
|
long |
length()
Number of elements in the vector; returned as a
long instead of
an int because Vecs support more than 2^32 elements. |
static OneChunkVec |
make(Vec v,
int cidx,
Futures fs) |
Vec |
masterVec() |
int |
nChunks()
Number of chunks, returned as an
int - Chunk count is limited by
the max size of a Java long[]. |
