All Known Implementing Classes:

public interface IFeatureSelection
extends Serializable

Provides access to members that control feature selection.

Remarks

IFeatureSelection is a very useful interface to manage or perform selection on a layer or to modify the way the selection is displayed.

The following methods and properties are useful to manage the selection:

The CombinationMethod property is not used.
SelectionSet returns a SelectionSet corresponding to the current selection on the layer.
Clear will clear an existing selection.
Add adds one single feature to the selection.
SelectFeatures will perform a selection based on a query filter. If nothing is used as a query filter all the features will be selected. You can also specify a combination method. The justOne parameter tells the search to stop once it has found one feature.
Call SelectionChanged after modifying SelectionSet to fire update events on the layer.

The following methods and properties are useful to modify the way the selection is displayed:

SelectionSymbol will return or set the symbol used to display selected features on the layer.
SetSelectionSymbol is a boolean used to indicate if the SelectionSymbol is used or not to draw the selection. For feature layers, this is similar to using the "Show selected features...with this symbol" option in the layer properties.
SelectionColor is equivalent to using the "Show selected features...with this color" option in the layer properties.
If BufferDistance is set to a value greater than 0, a buffer will be drawn around the selected features. This is similar to using the Buffer Selection tool that can be added to the map with the Customize command found in the Tools menu.
