Class TrcDataIntegrator<D>

java.lang.Object

trclib.dataprocessor.TrcDataIntegrator<D>

public class TrcDataIntegrator<D>
extends Object

This class does data integration for sensors that have one or more axes. Some value sensors such as gyros and accelerometers may need to integrate their data to provide heading from gyro rotation rate, and velocity or distance from accelerometer acceleration data. This class uses a periodic task to do integration and optionally double integration.

Constructor Details

TrcDataIntegrator

public TrcDataIntegrator(String instanceName,
 TrcSensor<D> sensor,
 D dataType,
 boolean doubleIntegration)

Constructor: Creates an instance of the object.

Parameters:

instanceName - specifies the instance name.

sensor - specifies the sensor object that needs integration.

dataType - specifies the data type to be integrated.

doubleIntegration - specifies true to do double integration, false otherwise.

TrcDataIntegrator

public TrcDataIntegrator(String instanceName,
 TrcSensor<D> sensor,
 D dataType)

Constructor: Creates an instance of the object.

Parameters:

instanceName - specifies the instance name.

sensor - specifies the sensor object that needs integration.

dataType - specifies the data type to be integrated.

Method Details

toString

public String toString()

This method returns the instance name.

Overrides:

toString in class Object

Returns:

instance name.

setEnabled

public void setEnabled(boolean enabled)

This method enables the data integrator. The data integrator is not automatically enabled when created. You must explicitly call this method to enable the data integrator.

Parameters:

enabled - specifies true for enabling the data processor, disabling it otherwise.

reset

public void reset(int index)

This method resets the indexed integratedData and doubleIntegratedData.

Parameters:

index - specifies the index.

reset

public void reset()

This method resets all integratorData and doubleIntegratedData.

getInputData

public TrcSensor.SensorData<Double> getInputData(int index)

This method returns the last indexed input data.

Parameters:

index - specifies the index.

Returns:

the last indexed input data.

getIntegratedData

public TrcSensor.SensorData<Double> getIntegratedData(int index)

This method returns the last indexed integrated data.

Parameters:

index - specifies the index.

Returns:

last indexed integrated data.

getDoubleIntegratedData

public TrcSensor.SensorData<Double> getDoubleIntegratedData(int index)

This method returns the last indexed double integrated data.

Parameters:

index - specifies the index.

Returns:

last indexed double integrated data.
