Name | Type | Description |
---|---|---|
_cursor | int Integer | cursor identifier (see TGIS_LayerVector.cursorOpen) |
_viewerCS | bool Boolean | if True an the layer has been attached to the Viewer then expected _extent units are in a Viewer coordinate space; otherwise expected _extent units are in a Layer coordinate space |
_extent | TGIS_Extent | extent of item to be found |
_query | string String | query which must be matched by item; closely mimics SQL WHERE clause; for examples you can use 'AGE >= 18'; empty (default) means that no all items will match. |
_shape | TGIS_Shape | if not nil, then only shapes matched _de9im matrix with _shape will be found |
_de9im | string String | DE-9IM matrix of comparison |
_skipDeleted | bool Boolean | set a skip deleted treatment; by default deleted items will be ignored |
Non internal version is unsafe in the event of any special overrides such as in TGIS_LayerVector.FindNext.
