                IMove[] moves)

Method Detail

getParent

public IGameNode getParent()

Description copied from interface: IGameNode

Returns the parent node or null if none exist.

Specified by:

getParent in interface IGameNode

getDepth

public int getDepth()

Description copied from interface: IGameNode

Returns the depth of the node in the game tree where 0 is the initial state.

Specified by:

getDepth in interface IGameNode

getState

public IGameState getState()

Description copied from interface: IGameNode

Returns the associated game state if it is still in memory. getState() may return null after compacting the game tree (which happens automatically) unless the nodes isPreserved() method returns true. IGame.regenerateNode(node) will restore the state in this case.

Specified by:

getState in interface IGameNode

setState

public void setState(IGameState state)

Description copied from interface: IGameNode

Sets the associated game state

Specified by:

setState in interface IGameNode

getMoves

public IMove[] getMoves()

Description copied from interface: IGameNode

Returns the moves that have lead to this game node.

Specified by:

getMoves in interface IGameNode

isPreserved

public boolean isPreserved()

Description copied from interface: IGameNode

Returns if this game nodes content should be preserved even in the case of compacting the game tree.

Specified by:

isPreserved in interface IGameNode

setPreserve

public void setPreserve(boolean preserve)

Description copied from interface: IGameNode

Sets whether this game nodes content should be preserved even in the case of compacting the game tree.

Specified by:

setPreserve in interface IGameNode

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getDiffCount

public static int[] getDiffCount(IGameState nodeA,

public static java.util.List<IFluent>[] getDiff(IGameState nodeA,
                                                IGameState nodeB)

isTerminal

public boolean isTerminal()

Description copied from interface: IGameNode

Returns whether this node is a terminal node or not.

Specified by:

isTerminal in interface IGameNode
