Class SimpleHex

java.lang.Object

SimpleHex

All Implemented Interfaces:

Hex, java.io.Serializable

public class SimpleHex
extends java.lang.Object
implements Hex, java.io.Serializable

This corresponds to a trio of rhombs, all of which share a common point and any two of which share a common edge. The union of three such rhombs is a hexagon, and that hexagon can be flipped by shifting all the rhombs to opposite sides of the hex.

Constant Field Values

rhombs

public final SimpleRhomb[] rhombs

The three rhombs in this hex.

Constructor Detail

SimpleHex

public SimpleHex(SimpleRhomb r0,
         SimpleRhomb r1,
         SimpleRhomb r2)

Public constructor. No checks. We make a hexagon out of the three given rhombs.

Method Detail

getJoins

public Rhomb[] getJoins()

Getter method.

Specified by:

getJoins in interface Hex

Returns:

A list of the three rhombs in this hex.

getHex

public SimplePolygon2D getHex()

Getter method.

Specified by:

getHex in interface Hex

Returns:

A polygon equal to the union of the three rhombs.

createSimpleHex

public SimpleHex createSimpleHex(java.util.List<Rhomb> allJoins,
                        java.util.List<Rhomb> newJoins)

Simplification method.

Specified by:

createSimpleHex in interface Hex

Returns:

This is already a SimpleHex, so just return this.

valid

public boolean valid()

Determine if this represents a hexagon--i.e., if the three rhombs all touch one another.

Specified by:

valid in interface Hex

Returns:

true if the three rhombs all touch one another.

contains

public boolean contains(Rhomb jj)

Determine if this contains a given Rhomb. This only contains SimpleRhombs, so any other type of Rhomb will return false.

Specified by:

contains in interface Hex

Parameters:

jj - The Rhomb we're looking for.

Returns:

true if this contains jj, false otherwise.

doubleOverlap

public boolean doubleOverlap(SimpleHex t)

Determine if this contains a SimpleRhomb in common with another SimpleHex.

Parameters:

t - The other SimpleHex.

Returns:

true if this contains a SimpleRhomb that t also contains.

equals

public boolean equals(java.lang.Object obj)

Two SimpleHexes are equal if they contain the same three SimpleRhombs.

Overrides:

equals in class java.lang.Object

flip

public java.util.List<Hex> flip()

Flip the Rhombs in this SimpleHex.

Specified by:

flip in interface Hex

Returns:

A list of all SimpleHexes created or destroyed by this flip.
