Enum Constant and Description
Bottom The (artificial) bottom element of the lattice, corresponding to the empty covector.
Cocircuit The first layer of the lattice, corresponding to points in the pseudosphere construction, or cocircuits of the oriented matroid.
Covector Normal faces, that are not Cocircuits or Topes.
Top The artificial top element of the face lattice.
Tope The top most (real) faces of lattice, corresponding to the topes of the construction.

Enum Constant Detail

Bottom

public static final Face.Type Bottom

The (artificial) bottom element of the lattice, corresponding to the empty covector.

Cocircuit

public static final Face.Type Cocircuit

The first layer of the lattice, corresponding to points in the pseudosphere construction, or cocircuits of the oriented matroid.

Covector

public static final Face.Type Covector

Normal faces, that are not Cocircuits or Topes.

Tope

public static final Face.Type Tope

The top most (real) faces of lattice, corresponding to the topes of the construction.

Top

public static final Face.Type Top

The artificial top element of the face lattice.

Method Detail

values

public static Face.Type[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Face.Type c : Face.Type.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Face.Type valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
