Member Function Documentation

◆ is_diagonal()

bool Triangulation::Edge_iterator::is_diagonal ( ) const

Returns: true if the current edge is a diagonal of the polygon

Definition at line 636 of file triangulation.cpp.

◆ is_outer_edge()

bool Triangulation::Edge_iterator::is_outer_edge ( ) const

Returns: true if the current edge is an artifical edge between a polygon vertex and the south-pole

Definition at line 626 of file triangulation.cpp.

◆ is_polygon_edge()

bool Triangulation::Edge_iterator::is_polygon_edge ( ) const

Returns: true if the current edge is an edge of the polygon curve

Definition at line 631 of file triangulation.cpp.

◆ line()

QLineF Triangulation::Edge_iterator::line ( ) const

Returns: an embedding of the edge in the plane

Definition at line 641 of file triangulation.cpp.

◆ segment()

Segment Triangulation::Edge_iterator::segment ( ) const

Returns: a Segment object, encoding the vertex indices

Definition at line 645 of file triangulation.cpp.

◆ vertex1()

Triangulation::Vertex_handle Triangulation::Edge_iterator::vertex1 ( ) const

Returns: a handle to the first vertex of the edge

Definition at line 618 of file triangulation.cpp.

◆ vertex2()

Triangulation::Vertex_handle Triangulation::Edge_iterator::vertex2 ( ) const

Returns: a handle to the second vertex of the edge
