DK11 for Delphi | GisLayerSqlDb2.TGIS_LayerSqlDb2Abstract.GetNewUid | Constructors | Fields | Methods | Properties

Gets the Uid for a new shape.

Available also on: .NET | Java.

Overrides TGIS_LayerVector.GetNewUid.

// Delphi
public
  function GetNewUid : TGIS_Uid; override;

// C++ Builder
public:
  virtual TGIS_Uid* GetNewUid(void);

Use this method to find the Uid for a new shape. It simply uses GetLastUid method to determine the next available id. See example in GetLastUid.

When using this operation, never call any function which uses FindFirst..FindNext (i.e., any function which iterates through the shapes using it). So never use inside an operation like Locate, PaintScope>, etc.
