Method Detail

• createLineLoop

  public static Runnable createLineLoop(Positionable positionable,
                                        long length,
                                        int dimension,
                                        Runnable action)

  Returns a loop, that moves the given positonable along a line, and executes the given operation for each pixel of the line. The method uses ClassCopyProvider, such that the returned loop can be optimised gracefully by the java just-in-time compiler. Aside from that, the result is functionally equivalent to:

    Runnable result = () -> {
       for (long i = 0; i < length; i++) {
           operation.run();
           positionable.fwd(dimension);
       }
       positionable.move(- length, dimension);
   }
   
   

  Parameters:

  positionable - Positionable that is moved (along a line). Defines the starting point of the line. After the loops execution the positionable is moved back to the starting point.

  length - Length of the line.

  dimension - Direction of the line.

  action - Operation that is executed for each pixel along the line.

  Returns:

  A Runnable that is functionally equivalent to:

• createIntervalLoop

  public static Runnable createIntervalLoop(Positionable positionable,
                                            Dimensions dimensions,
                                            Runnable action)

  Returns a Runnable containing a loop. The loop moves the given positionable over all the pixels of an interval. For each pixel of the interval the given operation is executed.

  Parameters:

  positionable - Positionable that is moved. Defines the minimum point of the interval. After the loops execution the positionable is moved back to the starting point.

  dimensions - Dimensions of the interval.

  action - Operation that is executed for each pixel of the interval.
