Constructor & Destructor Documentation

◆ ExistenceEventSource()

Constructor.

Parameters
[in]_pubthe publisher for SimEvents
[in]_worldthe word

Member Function Documentation

◆ Emit()

void Emit ( const std::string &  _data) const
inherited

emit an event with data to the internal publisher (and using the internal type)

Parameters
[in]_datathe JSON data related to this event.

◆ Init()

virtual void Init ( )
virtualinherited

Initialize the event.

Reimplemented in JointEventSource, and InRegionEventSource.

◆ IsActive()

virtual bool IsActive ( ) const
virtualinherited

An event source can be used to enable other events.

Inactive events do not generate an message when Emit is called.

Returns
true if the event is active

◆ Load()

virtual void Load ( const sdf::ElementPtr  _sdf)
virtual

Reads the model filter and event name.

Parameters
[in]_sdfthe element for this event source

Reimplemented from EventSource.

◆ OnExistence()

void OnExistence ( const std::string &  _model,
bool  _alive 
)

callback for gazebo event

Parameters
[in]_modelthe name of the model
[in]_alivetrue for spawn, false for delete
