Interface Dame

All Superinterfaces:

Cloneable, ModuleInterface, Serializable

All Known Implementing Classes:

DameImpl

public interface Dame

extends ModuleInterface

A class that implements the Dame interface is responsible for identifying dame points. It is expected that this module will be most useful in the endgame, so it does not need to perform complex analysis during the fuseki or middle game to try to figure out which groups are alive in identifying dame points. In the endgame, it will need to deal with issues such as not filling in points which are involved in a seki. Points which are shared as part of a seki and cannot be filled in are considered to be dame points.

Method Summary

boolean	canPointBePlayed(Point pt) Determine if a dame point can be played.
Set	getDamePoints() Get all points which are dame points.
boolean	isDamePoint(Point pt) Determine if the given point is a dame point.
