Method Detail

values

public static MooreNeighbourhood[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (MooreNeighbourhood c : MooreNeighbourhood.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static MooreNeighbourhood valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getPositionX

public int getPositionX()

Returns the relative X position to position (0, 0).

Specified by:

getPositionX in interface org.refcodes.graphical.PosXAccessor

Returns:

The relative position X to the (0,0) coordinate.

getPositionY

public int getPositionY()

Returns the relative Y position to position (0, 0).

Specified by:

getPositionY in interface org.refcodes.graphical.PosYAccessor

Returns:

The relative position Y to the (0,0) coordinate.

clockwiseNext

public MooreNeighbourhood clockwiseNext()

Returns the next clockwise state relative to the current state. Imagine the states as the positions on a clock, next to TOP would be TOP_RIGHT, next to TOP_RIGHT would be RIGHT, and so on (clockwise).

Specified by:

clockwiseNext in interface Neighbourhood<MooreNeighbourhood>

Returns:

The next state relative to the current state.

clockwisePrevious

public MooreNeighbourhood clockwisePrevious()

Returns the next anti-clockwise state relative to the current state. Imagine the states as the positions on a clock, next to TOP would be TOP_LEFT, next to TOP_LEFT would be LEFT, and so on (anti-clockwise).

Specified by:

clockwisePrevious in interface Neighbourhood<MooreNeighbourhood>

Returns:

The next state relative to the current state.
