SnapState enum

The previous snap candidate is no longer suitable and the current edit position is not snapped.

A snap has occurred to a SnapSource.

This value will be returned in the following cases:

• When moving from an unsnapped position to a position that's snapped to an existing snappable feature or graphic.
• When there is a change in snap candidate. For example, moving from a snap point on a polyline segment to its end vertex. This includes moving to a multiple candidate snap where one of the candidates was part of the previous snap.

Note that if the snap contains multiple candidates, where some are from features/graphics and some are from geometry guides, then SnapState.snappedToFeature will take priority over SnapState.snappedToGeometryGuide.

This value will not be returned in these cases:

• When there is a change in snap point but not snap candidate. For example, moving from a snap point on a polyline segment to another snap point on the same polyline segment.
• When moving around a feature or graphic such that the snap point and snap candidate do not change.

A snap has occurred to a geometry guide.

This value will be returned in the following cases:

• When moving from an unsnapped position to a position that's snapped to an existing geometry guide.
• When there is a change in snap candidate. For example, moving from a snap point on a geometry guide to a different geometry guide, or to a multiple candidate snap that involves the same guide.

This value will not be returned in these cases:

• When there is a change in snap point but not snap candidate. For example, moving from a snap point on a geometry guide to another snap point on the same geometry guide.
• When moving around a geometry guide such that the snap point and snap candidate do not change.
