HalfEdge.
Definition: HalfEdge.h:31
bool getForced() const
Returns, whether the HalfEdge belongs to a constrained edge or not.
Definition: HalfEdge.h:98
bool mForced
True, if the HalfEdge belongs to a constrained edge, false otherwise.
Definition: HalfEdge.h:42
int getNext() const
Returns the number of the next HalfEdge.
Definition: HalfEdge.h:83
void setNext(int n)
Sets the number of the next HalfEdge.
Definition: HalfEdge.h:108
void setPoint(int p)
Sets the number of point at which this HalfEdge points.
Definition: HalfEdge.h:113
bool mBreak
True, if the HalfEdge belongs to a break line, false otherwise.
Definition: HalfEdge.h:40
int getPoint() const
Returns the number of the point at which this HalfEdge points.
Definition: HalfEdge.h:88
int getDual() const
Returns the number of the dual HalfEdge.
Definition: HalfEdge.h:78
int mNext
Number of the next HalfEdge.
Definition: HalfEdge.h:36
void setDual(int d)
Sets the number of the dual HalfEdge.
Definition: HalfEdge.h:103
int mDual
Number of the dual HalfEdge.
Definition: HalfEdge.h:34
int mPoint
Number of the point at which this HalfEdge points.
Definition: HalfEdge.h:38
void setForced(bool f)
Sets the forced flag.
Definition: HalfEdge.h:123
HalfEdge()=default
Default constructor. Values for mDual, mNext, mPoint are set to -10 which means that they are undefin...
bool getBreak() const
Returns, whether the HalfEdge belongs to a break line or not.
Definition: HalfEdge.h:93
void setBreak(bool b)
Sets the break flag.
