Detailed Description

The base class for emitting SimEvents.

Constructor & Destructor Documentation

EventSource ( transport::PublisherPtr  _pub,
const std::string &  _type,
physics::WorldPtr  _world 
)

Constructor.

Parameters
[in]_pubthe publisher where the events are emitted
[in]_typethe type of event
[in]_worldPointer to the world (in order to get model refs, etc)
virtual ~EventSource ( )
virtual

Destructor.

Member Function Documentation

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

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

Parameters
[in]_datathe JSON data related to this event.
virtual void Init ( )
virtual

Initialize the event.

Reimplemented in JointEventSource, and InRegionEventSource.

virtual bool IsActive ( ) const
virtual

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

Load from an sdf element (with possible configuration data)

Parameters
[in]_sdfthe sdf element for the event in the world file

Reimplemented in JointEventSource, OccupiedEventSource, InRegionEventSource, SimStateEventSource, and ExistenceEventSource.

Member Data Documentation

std::string name
protected

Name of the event.

transport::PublisherPtr pub
protected

a way to send messages to the other topics (to the REST)

std::string type
