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,
System.Int32* left,
System.Int32* 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*
