AcBr::ErrorStatus getLoop( AcBrLoop& loop ) const;

Parameters |
Description |
|
loop |
Loop at the current position in the topological adjacency list |
The getLoop() list position query returns the loop at the current position in the vertex loop list. The loop object is instantiated by the caller and passed by reference for getLoop() to set.
Returns eUninitialisedObject if this traverser object is uninitialised.
Returns eBrepChanged if the associated AutoCAD object has been modified since the traverser was last set.
Returns Acad::eNotInDatabase if the loop is missing.
In the event of an error, the loop reference object is unchanged and is thus likely to be uninitialized.
