MoveLib

Class MoveLib

java.lang.Object
  MoveLib

All Implemented Interfaces:: GameConstants

class MoveLib
extends java.lang.Object
implements GameConstants

Field Summary
`static int`	`BOWL_A`
`static int`	`BOWL_B`
`static int`	`BOWL_C`
`static int`	`BOWL_D`
`private java.util.Hashtable`	`lib`
`static int[]`	`MOVE_ROOT`
`private int[]`	`parent` Parent is our linkage back to the previous move.

Constructor Summary
`(package private)`	`MoveLib()` To ease some of the painful process of learning, we load the library with some of the more obvious moves.

Method Summary
`(package private) int`	`getMove(int[] board)` getMove attempts to look up a move in the library, based on the current state of the board.
`(package private) void`	`lostGame()` lostGame trims back the move tree to the last guess made.
`(package private) void`	`resetParent()`
`(package private) int`	`storedMoves()` This returns the stored move count, which is displayed on the game board.
`java.lang.String`	`toString()` This has proven useful in debugging and thus, has been left in.

Field Detail

lib

private java.util.Hashtable lib

ran

private java.util.Random ran

parent

private int[] parent

Parent is our linkage back to the previous move. The value of the last move made will be added to the next in order to chain them together. This is used later when we have to purge branches of the tree that have proven themselves to be unuseful.

Constructor Detail

MoveLib

MoveLib()

To ease some of the painful process of learning, we load the library with some of the more obvious moves.

Method Detail

storedMoves

int storedMoves()

This returns the stored move count, which is displayed on the game board. In this way the user can see the move tree grow as moves are made, and shrink when the tree is pruned back.

toString

public java.lang.String toString()

This has proven useful in debugging and thus, has been left in.

resetParent

void resetParent()

getMove

int getMove(int[] board)

getMove attempts to look up a move in the library, based on the current state of the board. If none is found, a new random move is created, added to the library, and returned as if a move was found.

lostGame

void lostGame()

lostGame trims back the move tree to the last guess made. We flip it to force exploration of the untried branch.
