identify
Initiate an Identify operation on all graphics overlays.
Results are returned in top-to-bottom order.
The tolerance parameter determines the extent of the region used during the identify operation. This overload will return the single visible topmost graphic per overlay only. A tolerance of 0 tests just the physical pixel at screenCoordinate. Tolerance values above 0 are in DIPs and specify a circular region centered on screenCoordinate, with radius equal to tolerance. The maximum allowed tolerance value is 100 DIPs, resulting in an identify circle of diameter 200 DIPs.
The returnPopupsOnly parameter controls what properties are populated in the IdentifyGraphicsOverlayResult instances that are returned by the identify operation:
true: only IdentifyGraphicsOverlayResult.popups properties will be populated. Overlays without popups will be omitted.
false: IdentifyGraphicsOverlayResult.geoElements, IdentifyGraphicsOverlayResult.graphics, and IdentifyGraphicsOverlayResult.popups are populated, if the overlay has popups.
Return
A Result containing a List of IdentifyGraphicsOverlayResult containing one entry for each overlay in the view, or failure. Each entry holds a GraphicsOverlay, a List of GeoElement, and a List of Graphics
Since
200.0.0
Parameters
location on which to run identify in screen coordinates
extent of the region used during the identify operation
whether the graphics property of the results are populated
Initiate an Identify operation on all graphics overlays.
Results are returned in top-to-bottom order.
The tolerance parameter determines the extent of the region used during the identify operation. Any graphics that intersect this test region when rendered are returned, up to the maximumResults limit. A tolerance of 0 tests just the physical pixel at screenCoordinate. Tolerance values above 0 are in DIPs and specify a circular region centered on screenCoordinate, with radius equal to tolerance. The maximum allowed tolerance value is 100 DIPs, resulting in an identify circle of diameter 200 DIPs.
The returnPopupsOnly parameter controls what properties are populated in the IdentifyGraphicsOverlayResult instances that are returned by the identify operation:
true: only IdentifyGraphicsOverlayResult.popups properties will be populated. Overlays without popups will be omitted.
false: IdentifyGraphicsOverlayResult.geoElements, IdentifyGraphicsOverlayResult.graphics, and IdentifyGraphicsOverlayResult.popups are populated, if the overlay has popups.
