Syntax

// C#
public ITGIS_LayerVectorEnumeratorFactory Loop_5(
  ITGIS_Extent _extent,
  WideString _query,
  ITGIS_Shape _shape,
  WideString _de9im,
  WordBool _skipDeleted
);
' VisualBasic
Public Function Loop_5(
  ByVal _extent As ITGIS_Extent,
  ByVal _query As WideString,
  ByVal _shape As ITGIS_Shape,
  ByVal _de9im As WideString,
  ByVal _skipDeleted As WordBool
) As ITGIS_LayerVectorEnumeratorFactory
// Oxygene
public
  function Loop_5(
    _extent : ITGIS_Extent;
    _query : WideString;
    _shape : ITGIS_Shape;
    _de9im : WideString;
    _skipDeleted : WordBool
  ) : ITGIS_LayerVectorEnumeratorFactory;

Parameters

Name Type Description
_extent ITGIS_Extent extent of items to be found; expected _extent units are in a Layer coordinate space
_query WideString query which must be matched by item; closely mimics SQL WHERE clause; for examples you can use 'AGE >= 18'; empty (default) means that no items will match.
_shape ITGIS_Shape if not nil, then only shapes matched _de9im matrix with _shape will be found
_de9im WideString DE-9IM matrix of comparison
_skipDeleted WordBool set a skip deleted treatment; by default deleted items will be ignored

Result

Type Description
ITGIS_LayerVectorEnumeratorFactory Shape itself or nil.
