Constructor Detail

FlatteningPathIterator

public FlatteningPathIterator(PathIterator2ai<E> pathIterator,
                              double flatness,
                              int limit)

Constructor.

Parameters:

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 PathIterator2ai<E> restartIterations()

Description copied from interface: PathIterator2D

Replies a reset instance of this iterator.

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

Specified by:

restartIterations in interface PathIterator2ai<E extends PathElement2ai>

Specified by:

restartIterations in interface PathIterator2D<E extends PathElement2ai>

Returns:

the reset iterator.

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<E extends PathElement2ai>

next

public E next()

Specified by:

next in interface Iterator<E extends PathElement2ai>

remove

public void remove()

Specified by:

remove in interface Iterator<E extends PathElement2ai>

getWindingRule

public PathWindingRule getWindingRule()

Description copied from interface: PathIterator2D

Replies the winding rule for the path.

Specified by:

getWindingRule in interface PathIterator2D<E extends PathElement2ai>

Returns:

the winding rule for the path.

isPolyline

public boolean isPolyline()

Description copied from interface: PathIterator2D

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

Specified by:

isPolyline in interface PathIterator2D<E extends PathElement2ai>

Returns:

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

isCurved

public boolean isCurved()

Description copied from interface: PathIterator2D

Replies the path contains a curve.

Specified by:

isCurved in interface PathIterator2D<E extends PathElement2ai>

Description copied from interface: PathIterator2D

Replies the path has multiple parts, i.e. multiple MOVE_TO are inside. primitives.

Specified by:

isMultiParts in interface PathIterator2D<E extends PathElement2ai>

Returns:

true if the path has multiple move-to primitive, false otherwise.

isPolygon

public boolean isPolygon()

Description copied from interface: PathIterator2D

Replies the path is composed only by one MOVE_TO, a sequence of LINE_TO or QUAD_TO or CURVE_TO or ARC_TO, and a single CLOSE primitives.

Specified by:

isPolygon in interface PathIterator2D<E extends PathElement2ai>

Returns:
