Merges layer with an existing layer.
Syntax
// Java public void MergeLayer( TGIS_LayerVector _layer, TGIS_Extent _extent, TGIS_ShapeType _type, java.lang.String _scope, TGIS_Shape _shape, java.lang.String _de9im, bool _truncated, bool _restrict );
// Oxygene public procedure MergeLayer( _layer : TGIS_LayerVector; _extent : TGIS_Extent; _type : TGIS_ShapeType; _scope : String; _shape : TGIS_Shape; _de9im : String; _truncated : Boolean; _restrict : Boolean );
Parameters
| Name | Type | Description |
|---|---|---|
| _layer | TGIS_LayerVector | layer to be imported |
| _extent | TGIS_Extent | starting extent of layer - can't be zero sized |
| _type | TGIS_ShapeType | shape type supported by a layer; if gistypeUnknown is used then import will try to recognize shape on its own; |
| _scope | java.lang.String String | SQL query for which shape will be imported |
| _shape | TGIS_Shape | if not nil, then only shapes matched _de9im matrix with _shape will be found |
| _de9im | java.lang.String String | DE-9IM matrix of comparison |
| _truncated | bool Boolean | if True, then all shapes will be truncated in _extent; if False, only the shape visible in _extent will be imported ; |
| _restrict | bool Boolean | if True, any field structure modification will raise error, otherwise allow to resize fields |
Remarks
Remember to assign 'path' property to layer you want to import from for proper import a new layer to file.
Use this method to merge layers. Before the merge SaveData will be fired.
