Class StatComputer

Class Documentation

class StatComputer

Class used for processing a stream of voltage data, including weights.

Public Functions

StatComputer(const ska::pst::common::AsciiHeader &data_config, const ska::pst::common::AsciiHeader &weights_config, std::shared_ptr<StatStorage> storage)

Create instance of a Stat Computer object.

Parameters

  • data_config – the configuration current data stream involving the data block.

  • weights_config – the configuration current data stream involving the weights block.

  • storage – a shared pointer to the in memory storage of the computed statistics.

virtual ~StatComputer()

Destroy the Stat Computer object.

bool compute(const ska::pst::common::SegmentProducer::Segment &segment)

compute the statistics for block of data.

Parameters

segment – the segment of data and weights for which statistics are computed

Returns

true all of the input samples were processed, the stored statistics are valid

Returns

false input sampling was interrupted, the stored statistics are invalid

void initialise()

initialise the StatComputer class in readiness for computing data.

This method needs to be called after there has been a resize of the StatStorage, otherwise there the size of data may not be as expected.

void interrupt()

interrupt the computation of statistics from the segment.
