Detailed Description

Altimeter Sensor Class.

An altimeter sensor that reports vertical position and velocity readings over gz transport

Member Function Documentation

◆ HasConnections()

virtual bool HasConnections ( ) const
overridevirtual

Check if there are any subscribers.

Returns
True if there are subscribers, false otherwise

Reimplemented from Sensor.

◆ Init()

virtual bool Init ( )
overridevirtual

Initialize values in the sensor.

Returns
True on success

Reimplemented from Sensor.

◆ Load() [1/2]

virtual bool Load ( const sdf::Sensor &  _sdf)
overridevirtual

Load the sensor based on data from an sdf::Sensor object.

Parameters
[in]_sdfSDF Sensor parameters.
Returns
true if loading was successful

Reimplemented from Sensor.

◆ Load() [2/2]

virtual bool Load ( sdf::ElementPtr  _sdf)
overridevirtual

Load the sensor with SDF parameters.

Parameters
[in]_sdfSDF Sensor parameters.
Returns
true if loading was successful

Reimplemented from Sensor.

◆ SetPosition()

void SetPosition ( double  _pos)

Set the current z position of the altimeter.

Parameters
[in]_posZ position in meters

◆ SetVerticalReference()

void SetVerticalReference ( double  _reference)

Set the vertical reference position of the altimeter.

Parameters
[in]_refVerical reference position in meters

◆ SetVerticalVelocity()

void SetVerticalVelocity ( double  _vel)

Set the vertical velocity of the altimeter.

Parameters
[in]_velVertical velocity in meters per second

◆ Update() [1/3]

virtual bool Update ( const std::chrono::steady_clock::duration &  _now)
overridevirtual

Update the sensor and generate data.

Parameters
[in]_nowThe current time
Returns
true if the update was successfull

Implements Sensor.

◆ Update() [2/3]

virtual bool Update

Force the sensor to generate data.

This method must be overridden by sensors. Subclasses should not not make a decision about whether or not they need to update. The Sensor class will make sure Update() is called at the correct time.

If a subclass wants to have a variable update rate it should call SetUpdateRate().

A subclass should return false if there was an error while updating

Parameters
[in]_nowThe current time
Returns
true if the update was successfull
See also
SetUpdateRate()

◆ Update() [3/3]

bool Update

Update the sensor.

This is called by the manager, and is responsible for determining if this sensor needs to generate data at this time. If so, the subclasses' Update() method will be called.

Parameters
[in]_nowThe current time
[in]_forceForce the update to happen even if it's not time
Returns
True if the update was triggered (_force was true or _now >= next_update_time) and the sensor's bool Sensor::Update(std::chrono::steady_clock::time_point) function returned true. False otherwise.
Remarks
If forced the NextUpdateTime() will be unchanged.

◆ VerticalPosition()

double VerticalPosition ( ) const

Get the vertical position of the altimeter relative to the reference position.

Returns
Vertical position relative to referene position

◆ VerticalReference()

double VerticalReference ( ) const

Get the vertical reference position of the altimeter.

Returns
Verical reference position in meters

◆ VerticalVelocity()

double VerticalVelocity ( ) const

Get the vertical velocity of the altimeter.

Returns
Vertical velocity in meters per second
