Specified by:

getRowIndex in interface Row

Returns:

the index of the row

getNonZeroNum

public int getNonZeroNum()

Specified by:

getNonZeroNum in interface Row

Returns:

the number of non-zero cells in the current row

setLoadFactor

public void setLoadFactor(float factor)

Description copied from interface: Row

Some implementations of sparse matrix cache rows in memory. In this case, it is required to have a measure to determine if the row should be removed from the cache when the cache is full.

Specified by:

setLoadFactor in interface Row

Parameters:

factor - the measure of how this row is frequently used

getLoadFactor

public float getLoadFactor()

Specified by:

getLoadFactor in interface Row
