Method Detail

clockwiseNext

S clockwiseNext()

Returns the next clockwise state relative to the current state. Imagine the states as the positions on a clock, next to "12" would be "1", next to "1" would be "2", and so on (clockwise).

Returns:

The next state relative to the current state.

clockwisePrevious

S clockwisePrevious()

Returns the next anti-clockwise state relative to the current state. Imagine the states as the positions on a clock, next to "12" would be "11", next to "11" would be "10", and so on (anti-clockwise).

Returns:

The next state relative to the current state.

next

default S next(Rotation aRotation)

Returns the next neighborhood for the given rotation relative to the current state. Depending on the Rotation element provided, either clockwiseNext() (Rotation.CLOCKWISE) or clockwisePrevious() (Rotation.ANTI_CLOCKWISE) is called.

Parameters:

aRotation - The rotation direction to use when calculating the next neighborhood.

Returns:

The next state relative to the current state.
