public interface SingleGroup

extends Cloneable, Serializable

A class that implements this interface is computing information about a single group of stones, where a group of stones is defined as the maximal set of stones of one color that is captured as a unit.

Method Detail

isInSingleGroup

public boolean isInSingleGroup(Stone stone)

Return whether the stone is contained in this group.

Parameters:

stone - The stone in question.

Returns:

Return true if the stone is in the group, or false.

isLibertyOfSingleGroup

public boolean isLibertyOfSingleGroup(Point pt)

Return whether this point is a liberty of the group.

Parameters:

pt - The point in question.

Returns:

Return true if the point is empty and adjacent to the group, or false.

getAnyStone

public Stone getAnyStone()

Return one of the stones in the group. Some methods take a Stone as an argument, and so it may not matter which stone from the group is used. This provides a shortcut to calling getStones()[0].

Returns:

A Stone object.

getStones

public Stone[] getStones()

Get all of the stones in the group.

Returns:

An array of stone objects.

getTotalStones

public short getTotalStones()

Get the total number of stones in this group.

Returns:

The number of stones in this group.

getLiberties

public Point[] getLiberties()

Get all points which are liberties of this group.

Returns:

An array of Point objects.

getTotalLiberties

public short getTotalLiberties()

Get the total number of liberties for this group.

Returns:

The number of liberties for the group.

getAdjacentOpponentStones

public Stone[] getAdjacentOpponentStones()

Get all of the opponents stones adjacent to this group.

Returns:

An array of Stone objects.

getColor

public Color getColor()

Get the color of the stones in this group.

Returns:

A Color object.

getMaxX

public int getMaxX()

Get the largest horizontal value for a stone in this group.

Returns:

The horizontal value.

getMinX

public int getMinX()

Get the smallest horizontal value for a stone in this group.

Returns:

The horizontal value.

getMinY

public int getMinY()

Get the smallest vertical value for a stone in this group.

Returns:

The vertical value.

getMaxY

public int getMaxY()

Get the largest vertical value for a stone in this group.

Returns:

The vertical value.

recompute

public void recompute(Board board)

Recompute all information for this group.

clone

public Object clone()

Overrides:
