void AddAttachedDouble( String sName, double dValue )
String sName
The name for the attachment. The name can contain any characters. If an attachment with the specified name already exists, the existing attachment is replaced.
double dValue
The double-precision value to add as an attachment.
This method adds a double-precision value as an attachment to the DataObject. You can retrieve the attachment later by calling the method GetAttachedDouble.
The DataObject class enables you to add attachments to a DataObject. This enables you to associate additional information about the data in a DataObject with the DataObject itself. The DataObject does not use your attachments. Note that attachments exist only in memory. They are not stored when you store the DataObject.
declare DataObject dobj = DataObject.Create( "Example" ); x = rannor( 1:100 ); dobj.AddVar( "X", x ); dobj.AddAttachedDouble( "X Mean", x[:] ); mx = dobj.GetAttachedDouble( "X Mean", . ); print mx;
