ThinkGeo.MapSuite.Core.GoogleMapsLayer

Note: The page was created before Map Suite 10. Map Suite 10.0 organized many classes into new namespaces and assemblies as well as had a few minor breaks in compatibility. The majority of previously built code should work without modification assuming the new namespaces are added. For guidance on upgrading your existing code, please check out MapSuite 10 Upgrade Guide.

Represents an object that encapsulates a Google Map layer.

Parameters

OpenCore()

  • This method opens the Layer so that it is initialized and ready to use.
Remarks
  • This abstract method is called from the concrete public method Open. The open method plays an important role, as it is responsible for initializing the Layer. Most methods on the Layer will throw an exception if the state of the Layer is not opened. When the map draws each layer, the layer will be opened as one of its first steps; then, after it is finished drawing with that layer, it will close it. In this way, we are sure to release all resources used by the Layer. When implementing the abstract method, consider opening the FeatureSource or RasterSource. You will get a chance to close these in the Close method of the Layer.
Return Value
  • Type:Void
  • Description:None
Parameters

CloseCore()

  • This method closes the Layer and releases any resources it was using.
Remarks
  • This abstract method is called from the concrete public method Close. The close method plays an important role in the life cycle of the Layer. It may be called after drawing to release any memory and other resources that were allocated since the Open method was called. If you override this method, it is recommended that you take the following things into account: This method may be called multiple times, so we suggest you write the method so that that a call to a closed Layer is ignored and does not generate an error. We also suggest that in the Close you free all resources that have been opened. Remember that the object will not be destroyed, but will be re-opened possibly in the near future.
Return Value
  • Type:Void
  • Description:None
Parameters

DrawCore(GeoCanvas,Collection<SimpleCandidate>)

  • This method draws the Layer.
Remarks
  • This method is the concrete wrapper for the abstract method DrawCore. This method draws the representation of the layer based on the extent you provided. When implementing this abstract method, consider each feature and its column data values. You can use the full power of the GeoCanvas to do the drawing. If you need column data for a feature, be sure to override the GetRequiredColumnNamesCore and add the columns you need to the collection. In many of the styles, we add properties that allow the user to specify which field they need; then, in the GetRequiredColumnNamesCore, we read that property and add it to the collection.
Return Value
  • Type:Void
  • Description:None
Parameters
  • canvas
    • Type:GeoCanvas
    • Description:This parameter is the canvas object or a GeoImage to draw on.
  • labelsInAllLayers
    • Type:Collection<SimpleCandidate>
    • Description:This parameter represents the labels used for collision detection and duplication checking.
