Member Function Documentation

getData()

virtual std::vector<double> dfx::MeasurementData::getData ( )

pure virtual

Returns the numerical data associated with this MeasurmentData.

The vector can contain one or more values based upon the study definition and what the server is able to provide.

For instance, if the MeasurementData is for "HEART_RATE" this may be one value which would be a summary for the entire measurement chunk or it could be an estimated value per-frame of the measurement chunk.

Returns

a vector of bytes containing the data of the MeasurementData.

getDataProperty()

virtual std::string dfx::MeasurementData::getDataProperty ( const std::string &  key )

pure virtual

Returns a measurement data property by key.

Measurement data may include additional properties which are available based upon what is returned by getDataPropertyKeys().

This may include for instance "ID" which could be "HEART_RATE" if the signal this MeasurementData represents is associated with "HEART_RATE".

Returns

the value of the property, or an empty string if key doesn't exist.

getDataPropertyKeys()

virtual std::vector<std::string> dfx::MeasurementData::getDataPropertyKeys ( )

pure virtual

Returns a list of measurement data property keys that can be used with getDataProperty().

Returns

list of measurement data property keys
