IMapVisual.ResetCache

Syntax

ResetCache;

Description

The ResetCache method resets a data source cache.

Example

Executing the example requires a form with the following components: the Button component named Button1, the MapBox component named MapBox1, and the UiMap component named UiMap1. UiMap1 is a data source for MapBox1. The map must be connected to the UiMap1 component.

The example is a handler of the OnClick event for the Button1 component.

Add links to the ExtCtrls, Forms, and Map system assemblies.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Map: IMap;
    MapVisual: IMapVisual;
Begin
    Map := UiMap1.Map;
    MapVisual := Map.FindVisual("Bar0");
    If MapVisual <> Null Then
        MapVisual.ResetCache;
    End If;
End Sub Button1OnClick;

After executing the example the Bar0 indicator is searched. If the indicator is found, data source cache is reset for it.
