Method Detail

isHasLiveData

boolean isHasLiveData()
                      throws IOException,
                             AutomationException

Indicates whether the layer is being updated frequently with new data.

Product Availability

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

Returns:

The hasLiveData

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

isCanModifyDrawingDescription

boolean isCanModifyDrawingDescription()
                                      throws IOException,
                                             AutomationException

Indicate whether DrawingDescription can be modified.

Remarks

Indicates whether MapServer allows the client to change the renderer for the layer dynamically without restarting a mapservice. MapServer currently supports only FeatureLayer for changing its renderer dynamically.

When Symbol Level Drawing is enabled on a group layer, then none of the sub layers in the group layer's renderer is allowed to be modified. But if Symbol Level Drawing is set on a feature layer, then dynamic rendering is enabled on the layer.

Please note that when IMapServerInfo4::SupportsDynamicLayers is False, this property for a layer will return False regardless of layer type or above rules.
