All Implemented Interfaces:

Cloneable, Serializable

public class NumberedStone

extends Stone

implements Serializable

This class represents a stone and the move number it was made on. Note that while there are only 361 total Point objects and 1083 Stone objects ever created, a new NumberedStone object is created each time one is needed. Therefore, it may be less useful in applications such as lookahead search, where large numbers of objects are used.

Constructor Detail

NumberedStone

public NumberedStone(short num,
                     Color color,
                     int x,
                     int y)
              throws IllegalArgumentException

Create a new NumberedStone object.

Parameters:

num - The move number.

color - The color of the move.

x - The horizontal coordinate of the move.

y - The vertical coordinate of the move.

Throws:

IllegalArgumentException - Thrown if the x or y coordinates are out of range.

NumberedStone

public NumberedStone(short num,
                     Stone s)
              throws IllegalArgumentException

Create a new NumberedStone object.

Parameters:

num - The move number.

s - The stone which is the move.

Throws:

IllegalArgumentException - Thrown if the x or y coordinates are out of range.

NumberedStone

public NumberedStone(int num,
                     Stone s)
              throws IllegalArgumentException

Create a new NumberedStone object. This is just for convenience in case an int is passed in instead of a short.

Parameters:

num - The move number.

s - The stone which is the move.

Throws:

IllegalArgumentException - Thrown if the x or y coordinates are out of range.

Method Detail

getMoveNumber

public short getMoveNumber()

Get the number of the move.

Returns:

The move number.

toString

public String toString()

Get a String representation of the object.

Overrides:

toString in class Stone

Returns:

A String object which represents the object.

hashCode

public int hashCode()

Get a unique integer which represents this object. Two NumberedStone objects will have the same hash code value if and only if they have the same move number, color, and x and y coordinates. A NumberedStone object will never have the same hash code value as a Stone or Point object.

Overrides:

hashCode in class Stone

Returns:

An int which is the hashcode for this object.

equals

public boolean equals(Object o)

Compare this object with another for equality. They are considered equal if they are both of type NumberedStone, and have the same hash code value.

Overrides:

equals in class Stone

Parameters:

o - The object to be compared with this one.

Returns:

A boolean value which is true if the two objects are the same, or false.

clone

public Object clone()

Return a clone of this object.

Overrides:

clone in class Stone

Returns:

A NumberedStone object.
