IRelationResult.RelationElement Property

The ith element of the relation. The indexes refer to elements of the left and right operand geometry bags.

[Visual Basic .NET]
Public Sub RelationElement ( _
    ByVal i As Integer, _
    ByRef left As Integer, _
    ByRef right As Integer _
)
[C#]
public void RelationElement (
    int i,
    ref int left,
    ref int right
);
[C++]
HRESULT get_RelationElement(
  long i,
  long* left,
  long* right
);
[C++]

Parameters i i is a parameter of type long left [out] left is a parameter of type long right [out] right is a parameter of type long
