Constructor Detail

FlatteningPathIterator

public FlatteningPathIterator(Path3ai<?,?,E,?,?,?> path,
                              PathIterator3ai<? extends E> pathIterator,
                              double flatness,
                              int limit)

Constructor.

Parameters:

path - is the path.

pathIterator - is the path iterator that may be used to initialize the path.

flatness - the maximum allowable distance between the control points and the flattened curve

limit - the maximum number of recursive subdivisions allowed for any curved segment

Method Detail

restartIterations

public PathIterator3ai<E> restartIterations()

Description copied from interface: PathIterator3D

Replies a reset instance of this iterator.

The reset instance enables to restart iterations with the replied iterator.

Specified by:

Specified by:

restartIterations in interface PathIterator3D<E extends PathElement3ai>

Returns:

the reset iterator.

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<E extends PathElement3ai>

next

public E next()

Specified by:

next in interface Iterator<E extends PathElement3ai>

remove

public void remove()

Specified by:

remove in interface Iterator<E extends PathElement3ai>

getWindingRule

Description copied from interface: PathIterator3D

Replies the winding rule for the path.

Specified by:

getWindingRule in interface PathIterator3D<E extends PathElement3ai>

Returns:

the winding rule for the path.

isPolyline

public boolean isPolyline()

Description copied from interface: PathIterator3D

Replies the path is composed only by one MOVE_TO, and a sequence of LINE_TO primitives.

Specified by:

isPolyline in interface PathIterator3D<E extends PathElement3ai>

Returns:

true if the path does not contain curve primitives, false otherwise.
