## Constructor & Destructor Documentation

openvrml::vrml97_node::time_sensor_node::time_sensor_node | ( | const node_type & | type,
|  | const boost::shared_ptr< openvrml::scope > & | scope
| ) |

  | Construct. Parameters:
  | type | the node_type associated with the instance.
  | scope | the scope that the new node will belong to.

openvrml::vrml97_node::time_sensor_node::~time_sensor_node | ( |  | ) | throw ()`[virtual]`

| Destroy.

## Member Function Documentation

time_sensor_node * openvrml::vrml97_node::time_sensor_node::to_time_sensor | ( |  | ) | const`[virtual]`

| Cast to a time_sensor_node. Returns: a pointer to the object. Reimplemented from openvrml::node.

void openvrml::vrml97_node::time_sensor_node::update | ( | double | time | ) |

| Generate timer events. If necessary, events prior to the timestamp (inTime) are generated to respect stopTimes and cycleIntervals. The timestamp should never be increased. This assumes the event loop delivers pending events in order (ascending time stamps). Should inTime be modified? Should ensure continuous events are delivered before discrete ones (such as cycleTime, isActive).

void openvrml::vrml97_node::time_sensor_node::do_initialize | ( | double | timestamp | ) | throw (std::bad_alloc)`[private, virtual]`

  | Initialize. Parameters:
  | timestamp | the current time.
  Exceptions:
  | std::bad_alloc | if memory allocation fails.
Reimplemented from openvrml::node.

void openvrml::vrml97_node::time_sensor_node::do_shutdown | ( | double | timestamp | ) | throw ()`[private, virtual]`

  | Shut down. Parameters:
  | timestamp | the current time.
Reimplemented from openvrml::node.
