Method Detail

advance

protected void advance(Direction direction)
                throws InvalidMove

This advance() method does everything the base class advance() does, but adds a memory by closing the wall behind it (sort of like leaving a trail of bread).

Overrides:

advance in class Mouse

Parameters:

direction - the direction to advance.

Throws:

InvalidMove - the specified direction constitutes an invalid move. Either a wall exists in this direction, or it is a cell we just came from in our currenent traversal path (this requires usage of the retreat() method).

retreat

protected void retreat()
                throws NoSolutionFound

This retreat() method does everything the base class retreat() does, but adds a memory by closing the wall behind it (sort of like leaving a trail of bread).

Overrides:

retreat in class Mouse

Throws:

NoSolutionFound - either there is no solution to this maze, or we have a programming bug :-(
