Class

• <DRM Flashing Light Behaviour>

Superclass

• <DRM Light Rendering Behaviour>

Subclass

• None.

Definition

An instance of this DRM class specifies behaviour specific to a flashing light.

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, and shall be a non-negative value. It can be used to allow a collection of objects representing lights to appear asynchronous.

The duration field specifies the period of time, measured in seconds, that the light is on, and is therefore required to be less than the period field value.

Constraints

• Publishable Object

Example(s)

• Consider a <DRM Point> representing a warning light at a railroad crossing. The <DRM Point> has a <DRM Light Rendering Properties> component, which in turn has a <DRM Flashing Light Behaviour> and a <DRM Light Rendering Properties Control Link>. The <DRM Light Rendering Properties Control Link> is used to turn on the light, so that the light flashes when indicating that a train is approaching.
