ShapeFileFeatureLayer

Namespace: ThinkGeo.Core

This class represents a Layer backed by a Shape File.

public class ShapeFileFeatureLayer : FeatureLayer

Inheritance ObjectLayerFeatureLayerShapeFileFeatureLayer

Remarks:

None

Properties

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 ShapeFileFeatureLayer, we override this API and mark it as true.

public bool HasBoundingBox { get; }

Property Value

Boolean

Remarks:

The default implementation in the base class returns false.

UsingSpatialIndex

This property gets whether the Shape File FeatureSource has an index or not.

public bool UsingSpatialIndex { get; }

Property Value

EditTools

        This property gets the EditTools that allow you to easily edit InternalFeatures in the
        Feature Layer.

Remarks:

The EditTools are supplied as an easily accessible wrapper for the editing methods of the FeatureSource.

FeatureIdsToExclude

A collection of strings representing record id of features not to get in the Layer.

public Collection<string> FeatureIdsToExclude { get; }

Property Value

Collection<String>

Remarks:

This string collection is a handy place to specify what records not to get from the source. Suppose you have a shape file of roads and you want to hide the roads within a particular rectangle, simply execute GetFeaturesInsideBoundingBox() and add the id of the return features to the collection and forget about them. Since you can set this by Layer it makes is easy to determine what to and what not to.

QueryTools

public QueryTools QueryTools { get; protected set; }

Property Value

QueryTools

        This property gets the QueryTools that allow you to easily query Features from the
        Feature Layer.

Remarks:

FeatureSource

This property gets the FeatureSource for the FeatureLayer.

public FeatureSource FeatureSource { get; protected set; }

Property Value

FeatureSource
This property gets the FeatureSource for the FeatureLayer.

Remarks:

The FeatureSource is the provider of data to the FeatureLayer. There are different FeatureSource classes to match the various ways that feature data is stored. It is important that, when you inherit from the FeatureLayer, in the constructor you set the FeatureSource you want to use.

DrawingQuality

This property gets and sets the general drawing quality for the FeatureLayer's view.

public DrawingQuality DrawingQuality { get; set; }

Property Value

DrawingQuality

        This property gets the general drawing quality for the FeatureLayer's
        view.

Remarks:

The DrawingQuality enumeration allows you to control, in a macro sense, the drawing quality that will be used in the GeoCanvas. Each GeoCanvas, which is responsible for drawing of the features, may have its own specialized drawing quality properties. What the DrawingQuality enumeration does is define some general guidelines for each GeoCanvas. For example, if you set the DrawingQuality to HighSpeed, then inside of the PlatformGeoCanvas there is a profile for HighSpeed. This profile sets specific properties, such as the smoothing mode and composing drawing mode of the PlatformGeoCanvas. As each GeoCanvas may have different drawing quality properties, this offers a general way to control drawing quality and speed.

If you need complete control over how a specific GeoCanvas will draw, then you can set the DrawingQuality to Custom. This will tell the specific GeoCanvas to use the properties on its own object instead of one of the pre-defined profiles. If one of the profiles -- such as HighSpeed or HighQuality -- is set, then the specific GeoCanvas ignores its own properties for drawing quality.

ZoomLevelSet

This property gets and sets the ZoomLevelSet, which contains the specific zoom levels for the FeatureLayer.

public ZoomLevelSet ZoomLevelSet { get; set; }

Property Value

ZoomLevelSet

        This property gets the ZoomLevelSet, which contains the specific zoom levels for
        the FeatureLayer.

Remarks:

The ZoomLevelSet is a class that contains all of the ZoomLevels for the FeatureLayer. Each ZoomLevel contains the styles that are used to determine how to draw the InternalFeatures.

DrawingMarginInPixel

public float DrawingMarginInPixel { get; set; }

Property Value

Single

IsOpen

This property returns true if the Layer is open and false if it is not.

public bool IsOpen { get; }

Property Value

Boolean

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. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework.

DrawingTime

This property gets the last drawing time for the layer.

public TimeSpan DrawingTime { get; protected set; }

Property Value

String

IsVisible

This property gets and set the visible state of the layer.

public bool IsVisible { get; set; }

Property Value

Boolean

Remarks:

If this property is set to false, the layer will not draw. We ensure this in the Draw method. This is useful for legends and other controls that control the visibility of layers.

Methods

CloneDeepCore()

protected Layer CloneDeepCore()

Returns

Layer

Rebuild(String)

This method rebuilds the SHP, SHX, DBF, IDX and IDS files for the given shape file.

public static void Rebuild(string shapePathFilename)

Parameters

shapePathFilename String
This parameter is the shape file you want to rebuild.

Remarks:

This method rebuilds the SHP, SHX, DBF, IDX and IDS files for the given shape file. When we do editing we have optimized the updates so that we do not need to rebuild the entire shape file. This leads to the shape file being out of order which may cause it not to open in other tools. One optimization is if you update a record instead of rebuilding a new shape file we mark the old record as null and add the edited record at the end of the shape file. This greatly increases the speed of committing shape file changes but will over time unorder the shape file. In addition we do a delete the DBF file will simply mark the record deleted and not compact the space. Rebuilding the shape file will correctly order the SPX and SHX along with compacting the DBF file and rebuild any index with the same any of the shape file if it exists.

Note that if you have build custom index files where the name of the index differs from that of the shape file you will need to rebuild those manually using the BuildIndex methods.

If you choose you can pass in your own stream to represent the file. The stream can come from a variety of places such as isolated storage, a compressed file, and encrypted stream. When the Image is finished with the stream it will dispose of it so be sure to keep this in mind when passing the stream in. If you do not pass in a alternate stream the class will attempt to load the file from the file system using the PathFilename property.

DrawingFeatures

This event is raised when features are about to be drawn in the layer.

public event EventHandler<DrawingFeaturesEventArgs> DrawingFeatures;
