Member Function Documentation

void CN94Proposal::BoundaryTriangleBirth::execute (  Coloring &  c  )  [virtual]

Updates the supplied coloring according to this move. It is an error to call this method if the move is not valid for the supplied coloring. Parameters: c  a coloring to be updated Implements Arak::ColoringMove. Definition at line 217 of file cn94.cpp. References Arak::Coloring::BdEdgeHandle, Arak::Coloring::newBoundaryTriangle(), and PointerHandle< T >::valid().

void CN94Proposal::BoundaryTriangleBirth::reset (  Coloring::BdEdgeHandle  e, const Point &  u, const Point &  v, const Point &  w )

Resets this move with the new values. Parameters: e  the window edge u  the first boundary vertex of the new triangle v  the second boundary vertex of the new triangle w  the interior vertex of the new triangle Definition at line 206 of file cn94.cpp. References Arak::Coloring::BdEdgeHandle, Arak::Geometry::Point, and Arak::Coloring::VertexHandle. Referenced by Arak::CN94Proposal::sampleBoundaryTriangleBirth().

void CN94Proposal::BoundaryTriangleBirth::undo (  Coloring &  c  )  [virtual]

Updates the supplied Coloring so that the effects of performing this move are undone. The semantics of this method ensure that applying execute(Coloring&) and then undo(Coloring&) to the same coloring leaves the coloring invariant. It is an error to call this method if this undo is not valid for the supplied coloring. Parameters: c  a coloring to be updated Implements Arak::ColoringMove. Definition at line 225 of file cn94.cpp. References Arak::Coloring::deleteBdTriangle(), and PointerHandle< T >::valid().

Member Data Documentation

Coloring::BdEdgeHandle Arak::CN94Proposal::BoundaryTriangleBirth::edge [protected]

The window edge along which the triangle is created. This is set to NULL when the move is executed, and it is restored if the move is undone. Definition at line 524 of file cn94.hpp. Referenced by Arak::CN94Proposal::ll().

Point Arak::CN94Proposal::BoundaryTriangleBirth::u [protected]

The boundary vertices of the boundary triangle; these vertices lie along edge. Definition at line 530 of file cn94.hpp. Referenced by Arak::CN94Proposal::ll().

Point Arak::CN94Proposal::BoundaryTriangleBirth::v [protected]

The boundary vertices of the boundary triangle; these vertices lie along edge. Definition at line 530 of file cn94.hpp. Referenced by Arak::CN94Proposal::ll().

Coloring::VertexHandle Arak::CN94Proposal::BoundaryTriangleBirth::vh [protected]

A handle on the root vertex of the triangle created by the move. This is invalid unless the move has been executed; it is invalidated if the move is undone. Definition at line 542 of file cn94.hpp.

Point Arak::CN94Proposal::BoundaryTriangleBirth::w [protected]

The interior vertex of the boundary triangle. Definition at line 535 of file cn94.hpp.
