SCA_DelaySensor(SCA_ISensor)
============================

base class --- :class:`SCA_ISensor`

.. class:: SCA_DelaySensor(SCA_ISensor)

   The Delay sensor generates positive and negative triggers at precise time, 
   expressed in number of frames. The delay parameter defines the length of the initial OFF period. A positive trigger is generated at the end of this period.

   The duration parameter defines the length of the ON period following the OFF period.
   There is a negative trigger at the end of the ON period. If duration is 0, the sensor stays ON and there is no negative trigger.

   The sensor runs the OFF-ON cycle once unless the repeat option is set: the OFF-ON cycle repeats indefinately (or the OFF cycle if duration is 0).

   Use :class:`SCA_ISensor.reset` at any time to restart sensor.

   .. attribute:: delay

      length of the initial OFF period as number of frame, 0 for immediate trigger.

      :type: integer.

   .. attribute:: duration

      length of the ON period in number of frame after the initial OFF period.

      If duration is greater than 0, a negative trigger is sent at the end of the ON pulse.

      :type: integer

   .. attribute:: repeat

      1 if the OFF-ON cycle should be repeated indefinately, 0 if it should run once.

      :type: integer

   .. attribute:: repeatTimes

   Number of times the actuator will repeat.

   :type: integer.
