Member Function Documentation

size_t Count

(

)

const

Get number of data points in first statistic.

Technically you can have different numbers of data points in each statistic if you call InsertStatistic after InsertData, but this is not a recommended use case.

Returns

Number of data points in first statistic.

void InsertData

(

const double

_data

)

Add a new sample to the statistical measures.

Parameters

[in]

_data

New signal data point.

bool InsertStatistic

(

const std::string &

_name

)

Add a new type of statistic.

Parameters

[in]

_name

Short name of new statistic. Valid values include: "maxAbs" "mean" "rms"

Returns

True if statistic was successfully added, false if name was not recognized or had already been inserted.

bool InsertStatistics

(

const std::string &

_names

)

Add multiple statistics.

Parameters

[in]

_names

Comma-separated list of new statistics. For example, all statistics could be added with: "maxAbs,mean,rms"

Returns

True if all statistics were successfully added, false if any names were not recognized or had already been inserted.

std::map<std::string, double> Map

(

)

const

Get the current values of each statistical measure, stored in a map using the short name as the key.

Returns

Map with short name of each statistic as key and value of statistic as the value.

void Reset

(

)

Forget all previous data.
