Interface World

All Known Implementing Classes:

MazeWorld, SentenceWorld, SentenceWorldParallel

public interface World

Basic specification of a world, which ensures that all worlds have certain methods (functions) and can be built, traversed and can have a physical distance measure defined.

Method Summary

void	build() Allows a world to be built once all necessary aspects of it have been specified.
boolean	getIsBuilt() Allows you to determine if the world has been built yet or not.
State	getNewState(State oldState, Action action) Given a state and an action, returns the resulting state.
int	getNumberOfStates()
State	getStartingState()
java.util.List	getStateList() Returns a list of all the states (i.e.
boolean	isTerminalState(State state) Reports whether this particular state is a terminal state.
java.util.Iterator	stateIterator() Returns an object which lets you iterate over all states (positions) in the world.
java.lang.String	toText() Returns a text representation of the world, if possible.

Method Detail

build

void build()

toText

java.lang.String toText()

Returns a text representation of the world, if possible.

stateIterator

java.util.Iterator stateIterator()

getNumberOfStates

int getNumberOfStates()

getNewState

State getNewState(State oldState,
                  Action action)

Given a state and an action, returns the resulting state.

isTerminalState

boolean isTerminalState(State state)

Reports whether this particular state is a terminal state.
