virtual

destructor

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] _sdf SDF 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] _sdf SDF Sensor parameters.

Returns: true if loading was successful

Reimplemented from Sensor.

◆ MagneticField()

math::Vector3d MagneticField ( ) const

Get the magnetic field vector in body frame.

Returns: Magnetic field vector in body frame

◆ SetWorldMagneticField()

void SetWorldMagneticField ( const math::Vector3d & _field )

Set the magnetic field vector in world frame.

Parameters

[in] _field Magnetic field vector in world frame.

◆ SetWorldPose()

void SetWorldPose ( const math::Pose3d _pose )

Set the world pose of the sensor.

Parameters

[in] _pose Pose in world frame

◆ Update() [1/3]

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

overridevirtual

Update the sensor and generate data.

Parameters

[in] _now The 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] _now The 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]	_now	The current time
[in]	_force	Force the update to happen even if it's not time

Returns: True if the update was performed (_force was true or _now >= next_update_time or sensor had a pending trigger) 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.

◆ WorldMagneticField()

math::Vector3d WorldMagneticField ( ) const

Get the magnetic field vector in world frame.

Returns: Magnetic field vector in world frame

◆ WorldPose()

math::Pose3d WorldPose ( ) const

Get the world pose of the sensor.

Returns: Pose in world frame.
