The SEDRIS Data Representation Model
APPENDIX A - Classes Flashing Light Behaviour |
|---|
An instance of this DRM class specifies behaviour specific to a flashing light.
Consider a <Point> instance representing a warning light at a railroad crossing. The <Point> instance has a <Light Rendering Properties> component, which in turn has a <Flashing Light Behaviour> component and a <Light Rendering Properties Control Link> component. The <Light Rendering Properties Control Link> instance is used to turn on the light, so that the light flashes when indicating that a train is approaching.

The period field specifies the total period of time, measured in seconds, and including both the on and off parts of the flashing cycle.
The delay field specifies a delay period, measured in seconds, before the flashing behaviour is to begin. It can be used to allow a collection of DRM objects representing lights to appear asynchronous.
The duration field specifies the period of time, measured in seconds, that the light is on, and shall be less than the period field value.
