Constructor Detail

ArcNavigational.ArcNavigationalIterator

public ArcNavigational.ArcNavigationalIterator(AngleNavigational stepAngle,
                                               boolean isCounterclockwise,
                                               boolean isInclusive)

Creates a navigational angle iterator.

Parameters:

stepAngle - - the angle to move for each step

isCounterclockwise - - whether to step counterclockwise

isInclusive - - whether to include the end angle

Method Detail

resetToEnd

public void resetToEnd()

Sets the iterator to the end angle.

Overrides:

resetToEnd in class A_Arc.A_ArcIterator

resetToStart

public void resetToStart()

Sets the iterator to the start angle.

Overrides:

resetToStart in class A_Arc.A_ArcIterator

stepToNext

public AngleNavigational stepToNext()

Moves to the next angle in the forward direction and returns it. The concept of "next" depends on the step direction.

Overrides:

stepToNext in class A_Arc.A_ArcIterator

Returns:

the angle

stepToPrevious

public AngleNavigational stepToPrevious()

Moves to the next angle in the backward direction and returns it. The concept of "previous" depends on the step direction.

Overrides:

stepToPrevious in class A_Arc.A_ArcIterator

Returns:

the angle
