TGIS_Shape.Recreate(TGIS_Shape; Pointer; Boolean; TGIS_Uid; TGIS_LayerVector) method
DK11 for Delphi | GisLayerVector.TGIS_Shape.Recreate | Overloads | Constructors | Fields | Methods | Properties
Recreate an instance.
Syntax
// Delphi public procedure Recreate( const _source : TGIS_Shape; const _ptr : Pointer; const _mapped : Boolean; const _uid : TGIS_Uid; const _layer : TGIS_LayerVector ); overload; virtual;
// C++ Builder public: virtual void Recreate( TGIS_Shape* const _source, const void* _ptr, const bool _mapped, TGIS_Uid* const _uid, TGIS_LayerVector* const _layer ) /* overload */;
Parameters
| Name | Type | Description |
|---|---|---|
| _source | TGIS_Shape | If not nil, then the base shape will be based on this shape. Otherwise _ptr, _uid and _layer will be used. |
| _ptr | Pointer | Address in memory where shape data exists. |
| _mapped | Boolean | True if pointer is mapped to the file |
| _uid | TGIS_Uid | Unique identifier for shape. |
| _layer | TGIS_LayerVector | Reference to the layer on which the shape will be created. |
Remarks
Use this method to recreate an instance with new basic values. Needed for faster FindNext in mapped file shapes. In such a situation shapes will be "reused" in FindNext loop. See Create method for details and example.
