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
