Data Structures
class	HeapOfInteger
	This class implements a heap of integers. The most effective usage of it is first to add there all items, and then get top item and remove any items till it becomes empty. More...
class	Helper
	The abstract helper class. More...
struct	Link
	The Link structure. More...
Public Types
enum	LinkFlag {   LF_None = 0, LF_Fwd = 1, LF_Rev = 2, LF_Both = 3,   LF_Reversed = 4 }
	Orientation flags that can be attached to a link. More...
enum	ResultCode { RC_LoopsDone = 1, RC_HangingLinks = 2, RC_Failure = 4 }
typedef NCollection_List< Link >	ListOfLink
typedef ListOfLink	Loop
Public Member Functions
	Poly_MakeLoops (const Helper *theHelper, const Handle_NCollection_BaseAllocator &theAlloc=0L)
	Constructor. If helper is NULL then the algorithm will probably return a wrong result.
void	Reset (const Helper *theHelper, const Handle_NCollection_BaseAllocator &theAlloc=0L)
	It is to reset the algorithm to the initial state.
void	AddLink (const Link &theLink)
	Adds a link to the set. theOrient defines which orientations of the link are allowed.
void	ReplaceLink (const Link &theLink, const Link &theNewLink)
	Replace one link with another (e.g. to change order of nodes)
LinkFlag	SetLinkOrientation (const Link &theLink, const LinkFlag theOrient)
	Set a new value of orientation of a link already added earlier. It can be used with LF_None to exclude the link from consideration. Returns the old value of orienation.
Link	FindLink (const Link &theLink) const
	Find the link stored in algo by value.
Standard_Integer	Perform ()
	Does the work. Returns the collection of result codes.
Standard_Integer	GetNbLoops () const
	Returns the number of loops in the result.
const Loop &	GetLoop (Standard_Integer theIndex) const
	Returns the loop of the given index.
Standard_Integer	GetNbHanging () const
	Returns the number of detected hanging chains.
void	GetHangingLinks (ListOfLink &theLinks) const
	Fills in the list of hanging links.
