MGDwgDataSources.getKeyColumnType

Syntax

string getKeyColumnType() 

Description

Gets the DWG key column data type.

This method is not affected by the busy state.

Parameters

None

Returns

String - The key column data type. Values can be: Boolean, Byte, Date, Decimal, Double, Float, Integer, Numeric, SmallInt, String, Time, TimeStamp, UnsignedByte, UnsignedInteger, and UnsignedSmallInt.

We recommend that you do not use Float or Double types because of the inherent inaccuracies in comparing them.

Note that the Autodesk MapGuide Viewer API uses string values while the DWGFeatureDataSource KeyColumnType element in Map Window XML (MWX) files uses enumerated constants. For more information about MWX, refer to the Autodesk MapGuide Dynamic Authoring Toolkit Developer's Guide.

Error Codes

none

Example

This code is designed to work with the 1stfloorplanEx6.mwf file used by the Filter DWG Layers example:

function getProperties()
{
   // Get the map and selected features
   var map = getMap();
   var mapSel = map.getSelection();
   // Use the single map layer Floor Plan
   var mapLayer = map.getMapLayer("Floor Plan");
   // Get DWG data source object for the layer
   var mapLayerSetup = mapLayer.getLayerSetup();
   var dwgMapLayerDataSource = mapLayerSetup.getDwgDataSources();
   var keyColumnType = dwgMapLayerDataSource.getKeyColumnType();
}
