public abstract class DenseBlockDRB extends DenseBlock
DenseBlock.Type| Modifier and Type | Method and Description |
|---|---|
int |
blockSize()
Get the number of rows per block, except last one.
|
int |
blockSize(int bix)
Get the number of rows of the given block.
|
long |
countNonZeros()
Compute the number of non-zero values, which potentially
makes a full pass over the underlying blocks.
|
int |
countNonZeros(int r)
Compute the number of non-zero values for the given row,
which potentially makes a full pass over the underlying row.
|
long |
countNonZeros(int rl,
int ru,
int ol,
int ou)
Compute the number of non-zero values, which potentially
makes a full pass over the underlying blocks in the row range.
|
boolean |
isContiguous()
Indicates if the dense block has a single
underlying block, i.e., if numBlocks==1.
|
boolean |
isContiguous(int rl,
int ru)
Indicates if the dense block has a single
underlying block for the given row range.
|
int |
numBlocks()
Get the number of allocated blocks.
|
int |
pos(int r)
Get the position for a given row within
its associated block.
|
int |
pos(int[] ix)
Get the position for a given cell
within the associated block.
|
int |
pos(int r,
int c)
Get the position for a given row and column
within the associated block.
|
void |
reset(int rlen,
int[] odims,
double v)
Resets the dense block by setting the given value.
|
DenseBlock |
set(double v)
Set the given value for the entire dense block (fill).
|
DenseBlock |
set(int rl,
int ru,
int cl,
