<Polygon2D variable>.Within (Function)
Determines whether geometry A (2D polygon) is completely within geometry B (i.e., geometry B completely contains geometry A).
<Linestring2D variable>.AddPoint (Function)
Adds a new point to a 2D linestring.
<Polygon2D variable>.IsValid (Function)
Checks whether the specified 2D polygon is valid according to the OGC rules.
<Polygon2D variable>.SerializeWKT (Function)
Serializes a 2D polygon using the Well-Known Text (WKT) format.
<emailPOP3Session variable>.CloseSession (Function)
Closes a POP3 session.
<Polygon2D variable>.ConvexHull (Function)
Calculates the convex hull of the specified 2D polygon.
<Polygon2D variable>.Cover (Function)
Determines if geometry A (of type 2D polygon) covers geometry B.
<Polygon2D variable>.Disjoint (Function)
Determines whether two geometries are disjoint, i.e. whether their intersection is empty.
<Polygon2D variable>.Intersect (Function)
Checks whether the intersection of a 2D polygon and another geometry does not result in an empty set.
<Polygon2D variable>.Overlap (Function)
Determines if a 2D polygon overlaps another geometry.
<Polygon2D variable>.Correct (Function)
Returns a corrected version of the specified 2D polygon.
<emailPOP3Session variable>.StartSession (Function)
Starts a POP3 session.
<emailPOP3Session variable>.NbMessage (Function)
Returns the number of incoming messages on the email server (POP3 protocol only).
<Polygon2D variable>.Cross (Function)
Determines if a 2D polygon crosses another geometry.
<Polygon2D variable>.Touch (Function)
Determines whether a 2D polygon touches another geometry.
<Polygon2D variable>.Contain (Function)
Determines if geometry A (of type 2D polygon) contains geometry B.
<Polygon2D variable>.Difference (Function)
Returns a geometry representing the difference between a 2D polygon and another geometry.
<Polygon2D variable>.Union (Function)
Returns a geometry corresponding to the union between a 2D polygon and another geometry.
