Provides access to properties and methods needed to manage temporal reference information for a dataset.
The Temporal Reference interface provides a standard way to define the temporal reference of data. This interface provides the necessary properties to exploit data in two modes: real-time and fixed-time (historical). Real-time mode uses the system clock as the temporal perspective and issues update events at the frequency dictated by the update frequency property. The time is further filtered to a period of time from the current time to a time in the past equal to the period property. This provides all of the required properties to define a temporal reference.
| Description | ||
|---|---|---|
 |
TemporalMode | Controls the behavior of temporal reference to reflect real-time or playback mode. |
|
TemporalPeriod | Used by the temporal renderer property page to determine the default time period for the temporal legend classes. |
|
TemporalPeriodUnits | Describes the temporal units that define the temporal period property. |
|
TemporalPerspective | Timestamp used by the temporal renderer to compare its time ranges stored in the temporal legend's temporal classes. |
 |
TemporalPerspectiveAsDate | The current temporal perspective in COleDateTime format, so the temporal perspective can be retrieved from VB. |
| CoClasses and Classes | Description |
|---|---|
| TemporalReference | Maintains temporal perspective on data and notifies all clients when the value changes. |
