delaunay::edge::edge (const vector2 & v0, const vector2 & v1) [inline]

The only constructur for an edge.

Parameters:

v0	a point at one end of the line segment
v1	the point at the other end of the line segment

Postconditions:

 assert( this->vertex(0) == v0 );
 assert( this->vertex(1) == v1 );

Definition at line 496 of file delaunay.h.

delaunay::edge::~edge (void) [inline]

Definition at line 511 of file delaunay.h.

const vector2 & delaunay::edge::vertex (const unsigned i) const [inline]

Get one of the points at the ends of the line segment.

Parameters:

i	which of the two points to get

Returns:

the requested point

Preconditions:

 assert( i == 0 || i == 1 );

Definition at line 518 of file delaunay.h.

Friends And Related Function Documentation

bool operator== (const edge & a, const edge & b) [friend]

Compare two edge objects for equality.

Parameters:

a	one of the two edge objects to compare
b	the other edge object

Returns:

true iff the two edge objects are equal

Invariants:

The ordering of the two points that define the edge is not important:

 assert( edge(a, b) == edge(a, b) );
 assert( edge(a, b) == edge(b, a) );

Otherwise, two edge objects are not equal.
