Description

The factory creates collections of event interval lists.

Object Model

Public Methods

Create	Create and register an event interval collection using specified name, description, and type.
CreateEventIntervalCollectionLighting	Create an event interval collection defined by computing sunlight, penumbra and umbra intervals as seen at specified location using specified selection of eclipsing bodies.
CreateEventIntervalCollectionSatisfaction	Create an event interval collection containing intervals during which condition set is satisfied.
CreateEventIntervalCollectionSignaled	Create an event interval collection recorded at target clock location by performing signal transmission of original interval list collection between base and target clock locations.
IsTypeSupported	Returns whether the specified type is supported.

Example

Determine if the specified event interval collection type is supported.
