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. As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework. === Return Value === ^ Return Type ^ Description ^ | Void | | === Parameters === ^ Name ^ Type ^ Description ^ [[#Public Methods|Go Back]] ==== Draw(GeoCanvas, Collection) ==== 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.

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.

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.

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 to 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 === ^ Return Type ^ Description ^ | Void | | === Parameters === ^ Name ^ Type ^ Description ^ | canvas | [[ThinkGeo.MapSuite.WindowsPhoneCore.GeoCanvas|GeoCanvas]] | This parameter is the canvas object or a GeoImage to draw on. | | labelsInAllLayers | Collection<[[ThinkGeo.MapSuite.WindowsPhoneCore.SimpleCandidate|SimpleCandidate]]> | This parameter are the labels used for collision detection and duplication checking. | [[#Protected Methods|Go Back]] ==== DrawException(GeoCanvas, Exception) ==== This method will draw on the canvas when the layer.Draw throw exception and the DrawExceptionMode is set to DrawException instead of ThrowException. === Remarks === This method can be overriden its logic by rewrite the DrawExceptionCore. === Return Value === ^ Return Type ^ Description ^ | Void | | === Parameters === ^ Name ^ Type ^ Description ^ | canvas | [[ThinkGeo.MapSuite.WindowsPhoneCore.GeoCanvas|GeoCanvas]] | The target canvas to draw the layer. | | e | Exception | The exception thrown when layer.Draw(). | [[#Protected Methods|Go Back]] ==== DrawExceptionCore(GeoCanvas, Exception) ==== This method will draw on the canvas when the layer.Draw throw exception and the DrawExceptionMode is set to DrawException instead of ThrowException. === Return Value === ^ Return Type ^ Description ^ | Void | | === Parameters === ^ Name ^ Type ^ Description ^ | canvas | [[ThinkGeo.MapSuite.WindowsPhoneCore.GeoCanvas|GeoCanvas]] | The target canvas to draw the layer. | | e | Exception | The exception thrown when layer.Draw(). | [[#Protected Methods|Go Back]] ==== Finalize() ==== === Return Value === ^ Return Type ^ Description ^ | Void | | === Parameters === ^ Name ^ Type ^ Description ^ [[#Protected Methods|Go Back]] ==== GetBoundingBoxCore() ==== This method returns the bounding box of the Layer. === Remarks === This method returns the bounding box of the Layer. === Return Value === ^ Return Type ^ Description ^ | [[ThinkGeo.MapSuite.WindowsPhoneCore.RectangleShape|RectangleShape]] | This method returns the bounding box of the Layer. | === Parameters === ^ Name ^ Type ^ Description ^ [[#Protected Methods|Go Back]] ==== MemberwiseClone() ==== === Return Value === ^ Return Type ^ Description ^ | Object | | === Parameters === ^ Name ^ Type ^ Description ^ [[#Protected Methods|Go Back]] ==== OnDrawingProgressChanged(DrawingProgressChangedEventArgs) ==== === Return Value === ^ Return Type ^ Description ^ | Void | | === Parameters === ^ Name ^ Type ^ Description ^ | e | [[ThinkGeo.MapSuite.WindowsPhoneCore.DrawingProgressChangedEventArgs|DrawingProgressChangedEventArgs]] | | [[#Protected Methods|Go Back]] ==== 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, it will open the layer as one of its first steps; then, after it is finished drawing with that layer, it will close it.

This is useful for determining the speed of various layers. === Return Value === ^ Return Type ^ | TimeSpan | [[#Public Properties|Go Back]] ==== HasBoundingBox ==== This property checks to see if a Layer has a BoundingBox or not. If it has no BoundingBox, it will throw an exception when you call the GetBoundingBox() and GetFullExtent() APIs. In GroupLayer, we override this API and mark it as true. === Remarks === The default implementation in the base class returns false. === Return Value === ^ Return Type ^ | Boolean | [[#Public Properties|Go Back]] ==== IsOpen ==== This property returns true if the Layer is open and false if it is not. === Remarks === This method is the concrete wrapper for the abstract method IsOpenCore. Various methods on the Layer require that it be in an open state. If one of those methods is called when the state is not open, then the method will throw an exception. To enter the open state, you must call the Layer Open method. The method will raise an exception if the current Layer is already open. As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs.

We ensure this in the Draw method. This is useful for legends and other controls that control the visibility of layers. === Return Value === ^ Return Type ^ | Boolean | [[#Public Properties|Go Back]] ==== Layers ==== This property gets the layers you want to use. === Remarks === This property gets the layers you want to use. === Return Value === ^ Return Type ^ | [[ThinkGeo.MapSuite.WindowsPhoneCore.GeoCollection|GeoCollection]]<[[ThinkGeo.MapSuite.WindowsPhoneCore.Layer|Layer]]> | [[#Public Properties|Go Back]] ==== Name ==== This property gets and sets the name for the layer. === Remarks === The name is user defined. It is useful to set, as it may be used for higher level components such as legends, etc. === Return Value === ^ Return Type ^ | String | [[#Public Properties|Go Back]] ===== Protected Properties ===== ==== IsOpenCore ==== This property returns true if the Layer is open and false if it is not. === Remarks === Various methods on the Layer require that it be in an open state.
