TGIS_LayerVector.PrepareExportFieldNames(Integer; Boolean) method
DK11 for Delphi | GisLayerVector.TGIS_LayerVector.PrepareExportFieldNames | Overloads | Constructors | Fields | Methods | Properties | Events
Prepares field names to export.
Syntax
// Delphi public procedure PrepareExportFieldNames( const _maxwidth : Integer; const _forced : Boolean ); overload; virtual;
// C++ Builder public: virtual void PrepareExportFieldNames( const int _maxwidth, const bool _forced ) /* overload */;
Parameters
| Name | Type | Description |
|---|---|---|
| _maxwidth | Integer | max width of field; should be >= 4 |
| _forced | Boolean | if _false (default) export names will be constructed for new fields; otherwise saved fields will be ignored |
Remarks
Use this method to prepare an export of field names to meet maxwidth criteria. The procedure will also perform basic name adjustment (remove non-ascii letters, etc.).
If a field name is empty, then it will be named to 'FIELD'.
If first letter of the field is not alphanumeric, then the first letter will be changed to 'F'.
If a field is longer then a specified value, then the field will be truncated.
If a field after such changes already exists, then the field will be renamed to nameXX (where XX means 00, 01, etc. in hexadecimal).
