  procedure cursorFirstInternal(
    _cursor : Integer;
    _viewerCS : Boolean;
    _extent : TGIS_Extent;
    _query : String;
    _shape : TGIS_Shape;
    _de9im : String;
    _skipDeleted : Boolean
  ); virtual;

Parameters

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 java.lang.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 java.lang.String
String
DE-9IM matrix of comparison
_skipDeleted bool
Boolean
set a skip deleted treatment; by default deleted items will be ignored
