Constructor Detail

Simplex

public Simplex(java.util.Collection collection)

Constructor.

Parameters:

collection - a Collection holding the Simplex vertices

Throws:

java.lang.IllegalArgumentException - if there are duplicate vertices

Simplex

public Simplex(java.lang.Object[] vertices)

Constructor.

Parameters:

vertices - the vertices of the Simplex.

Throws:

java.lang.IllegalArgumentException - if there are duplicate vertices

Method Detail

toString

public java.lang.String toString()

String representation.

Overrides:

toString in class java.util.AbstractCollection

Returns:

the String representation of this Simplex

dimension

public int dimension()

Dimension of the Simplex.

Returns:

dimension of Simplex (one less than number of vertices)

isNeighbor

public boolean isNeighbor(Simplex simplex)

True iff simplices are neighbors. Two simplices are neighbors if they are the same dimension and they share a facet.

Parameters:

simplex - the other Simplex

Returns:

true iff this Simplex is a neighbor of simplex

facets

public java.util.List facets()

Report the facets of this Simplex. Each facet is a set of vertices.

Returns:

an Iterable for the facets of this Simplex

boundary

public static java.util.Set boundary(java.util.Set simplexSet)

Report the boundary of a Set of Simplices. The boundary is a Set of facets where each facet is a Set of vertices.

Returns:

an Iterator for the facets that make up the boundary

iterator

public java.util.Iterator iterator()

Specified by:

iterator in interface java.lang.Iterable

Specified by:

iterator in interface java.util.Collection

Specified by:

iterator in interface java.util.Set

Specified by:

iterator in class java.util.AbstractCollection

Returns:

Iterator for Simplex's vertices.

size

public int size()

Specified by:

size in interface java.util.Collection

Specified by:

size in interface java.util.Set

Specified by:

size in class java.util.AbstractCollection

Returns:

the size (# of vertices) of this Simplex

hashCode

public int hashCode()

Specified by:

hashCode in interface java.util.Collection

Specified by:

hashCode in interface java.util.Set

Overrides:

hashCode in class java.util.AbstractSet

Returns:

the hashCode of this Simplex

equals

public boolean equals(java.lang.Object o)

We want to allow for different simplices that share the same vertex set.

Specified by:

equals in interface java.util.Collection

Specified by:

equals in interface java.util.Set

Overrides:

equals in class java.util.AbstractSet

Returns:

true for equal Simplices
