• Triangulation

  public Triangulation(Simplex simplex)

  Constructor.

  Parameters:

  simplex - the initial Simplex.

Method Detail

• toString

  public String toString()

  String representation. Shows number of simplices currently in the Triangulation.

  Overrides:

  toString in class Object

  Returns:

  a String representing the Triangulation

• size

  public int size()

  Size (# of Simplices) in Triangulation.

  Returns:

  the number of Simplices in this Triangulation

• contains

  public boolean contains(Simplex simplex)

  True iff the simplex is in this Triangulation.

  Parameters:

  simplex - the simplex to check

  Returns:

  true iff the simplex is in this Triangulation

• iterator

  public Iterator iterator()

  Iterator.

  Returns:

  an iterator for every Simplex in the Triangulation

• printStuff

  public void printStuff()

  Print stuff about a Triangulation. Used for debugging.

• neighborOpposite

  public Simplex neighborOpposite(Object vertex,
                                  Simplex simplex)

  Report neighbor opposite the given vertex of simplex.

  Parameters:

  vertex - a vertex of simplex

  simplex - we want the neighbor of this Simplex

  Returns:

  the neighbor opposite vertex of simplex; null if none

  Throws:

  IllegalArgumentException - if vertex is not in this Simplex

• neighbors

  public Set neighbors(Simplex simplex)

  Report neighbors of the given simplex.

  Parameters:

  simplex - a Simplex

  Returns:

  the Set of neighbors of simplex

• update

  public void update(Set oldSet,
                     Set newSet)

  Update by replacing one set of Simplices with another. Both sets of simplices must fill the same "hole" in the Triangulation.

  Parameters:

  oldSet - set of Simplices to be replaced

  newSet - set of replacement Simplices
