Method Details

buildHistogramComponentBlock

DoubleBlock buildHistogramComponentBlock(HistogramBlock.Component component)

Returns a block holding the specified component of the histogram at each position. The number of positions in the returned block will be exactly equal to the number of positions in this block. If a position is null in this block, it will also be null in the returned block.
The caller is responsible for closing the returned block.

Parameters:

component - the component to extract

Returns:

the block containing the specified component
