Constructor & Destructor Documentation

◆ SegmentsIterator()

plask::SegmentsIterator::SegmentsIterator ( const std::vector< std::vector< Vec< 2, int > > > & segments )

inline

Construct iterator.

After first next() call iterator will point to the first point.

Parameters

segments vector of closed polygons, each consist of number of successive verticles, one side is between last and first vertex. These polygons are xored. Sides must not cross each other.

Definition at line 313 of file lattice.cpp.

Member Function Documentation

◆ next()

bool plask::SegmentsIterator::next ( )

inline

Go to next segment.

Set new values of first, second.

Returns: true only if next segment exists.
