Constructor Detail

RandomImpl

public RandomImpl(GameId id,
                  ModuleName name)
           throws InternalErrorException

Create the RandomImpl object.

Parameters:

id - The game id.

name - The name of this module.

Throws:

InternalErrorException - Thrown if an error occurs for any reason.

Method Detail

getRandomShort

public short getRandomShort(short total)

This method returns a number between 0 and total - 1. This method can be used for tasks such as choosing which fuseki to play. Modules should use this method instead of using their own Random class because it allows for reproducibility of results for debugging purposes.

Specified by:

getRandomShort in interface Random

Parameters:

total - The number of choices.

Returns:

A short between 0 and total - 1.

generateMove

public void generateMove(Module[] modules)

Generate the rated moves. The result of this call is that the rated move array is filled in.

Specified by:

generateMove in class Module

Parameters:

modules - The modules that this method uses.

getDebugInformation

public Debug[] getDebugInformation(DebugType[] types)

Get the debug information for this module.

Specified by:

getDebugInformation in class Module

Parameters:

types - The debug types that the caller can use.

Returns:

An array of Debug objects.

getDebugTypes

public DebugType[] getDebugTypes()

Get the debug types that this module supports.

Specified by:

getDebugTypes in class Module

Returns:

An array of DebugType objects.

getMoves

public RatedMove[] getMoves()

Get the rated moves for this module.

Specified by:

getMoves in interface ModuleInterface

Specified by:

getMoves in class Module

Returns:

An array of RatedMove objects.

getRequiredModuleList

public ModuleType[] getRequiredModuleList()

Get the modules that this module requires.

Specified by:

getRequiredModuleList in class Module

Returns:

An array of ModuleType objects.

makeMove

public void makeMove(Move move,
                     Module[] modules)

Update this module with the move. This module doesn't do anything on a move being made, except for clearing out some variables set in generateMove().

Specified by:

makeMove in class Module

Parameters:

move - The last move made.

modules - The modules that this module requires.

clone

public Object clone()

Override the Object.clone() method.

Specified by:

clone in interface ModuleInterface

Overrides:

clone in class Module

Returns:

A RandomImpl object which is a clone of this one.
