Method Detail

getLayerCount

int getLayerCount()
                  throws IOException,
                         AutomationException

Symbol layer count.

Description

LayerCount returns the number of constituent symbols.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Returns:

The count

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getLayer

IMarkerSymbol getLayer(int index)
                       throws IOException,
                              AutomationException

Marker symbol per index position.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Parameters:

index - The index (in)

Returns:

A reference to a com.esri.arcgis.display.IMarkerSymbol

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

addLayer

void addLayer(IMarkerSymbol markerLayer)
              throws IOException,
                     AutomationException

Add marker symbol layer.

Description

AddLayer adds the specified marker symbol to a IMultiLayerMarkerSymbol . This symbol will draw in the topmost position in the IMultiLayerMarkerSymbol. The layer can be of any type supported by the IMarkerSymbol interface except types implementing IMultiLayerMarkerSymbol. In this case an E_INVALIDARG HRESULT will be thrown. Therefore, a MultiLayerMarkerSymbol cannot be imbeded within another MultiLayerMarkerSymbol.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Parameters:

markerLayer - A reference to a com.esri.arcgis.display.IMarkerSymbol (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

deleteLayer

void deleteLayer(IMarkerSymbol markerLayer)
                 throws IOException,
                        AutomationException

Delete marker symbol layer.

Description

DeleteLayer deletes the specified layer in a IMultiLayerMarkerSymbol . Use LayerCount beforehand to determine how many layers currently exist in a IMultiLayerMarkerSymbol .

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Parameters:

markerLayer - A reference to a com.esri.arcgis.display.IMarkerSymbol (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

moveLayer

void moveLayer(IMarkerSymbol markerLayer,
               int toIndex)
               throws IOException,
                      AutomationException

Change layer index position.

Description

MoveLayer moves the marker symbol to the specified index in an IMultiLayerMarkerSymbol 's list of constituent symbols. Use LayerCount beforehand to determine how many layers currently exist in a IMultiLayerMarkerSymbol . Note that the marker symbol you specify should be determined using the Layer method on the current IMultiLayerMarkerSymbol .
