Interface Instant

All Superinterfaces:

Separation, TemporalGeometricPrimitive, TemporalObject, TemporalOrder, TemporalPrimitive

All Known Implementing Classes:

DefaultInstant

@UML(identifier="TM_Instant",
     specification=ISO_19108)
public interface Instant
extends TemporalGeometricPrimitive

A zero-dimensional geometric primitive that represents position in time, equivalent to a point in space.

Author:

Stephane Fellah (Image Matters), Alexander Petkov TODO There is a bit of a conflict in the spec document as to what should be returned for "position." The diagram shows that Position should be returned, while the text in the document demands that TemporalPosition should represent position in time.
