Creates a PolylineShapeIterator.

Method Detail

currentSegment

public int currentSegment(double[] coords)

Returns the coordinates and type of the current path segment in the iteration. The return value is the path segment type: SEG_MOVETO, SEG_LINETO, SEG_QUADTO, SEG_CUBICTO, or SEG_CLOSE. A double array of length 6 must be passed in and may be used to store the coordinates of the point(s). Each point is stored as a pair of double x,y coordinates. SEG_MOVETO and SEG_LINETO types will return one point, SEG_QUADTO will return two points, SEG_CUBICTO will return 3 points and SEG_CLOSE will not return any points.

Specified by:

currentSegment in interface java.awt.geom.PathIterator

currentSegment

public int currentSegment(float[] coords)

Returns the coordinates and type of the current path segment in the iteration. The return value is the path segment type: SEG_MOVETO, SEG_LINETO, SEG_QUADTO, SEG_CUBICTO, or SEG_CLOSE. A double array of length 6 must be passed in and may be used to store the coordinates of the point(s). Each point is stored as a pair of double x,y coordinates. SEG_MOVETO and SEG_LINETO types will return one point, SEG_QUADTO will return two points, SEG_CUBICTO will return 3 points and SEG_CLOSE will not return any points.

getWindingRule

public int getWindingRule()

Return the winding rule for determining the insideness of the path.

Specified by:

getWindingRule in interface java.awt.geom.PathIterator

See Also:

PathIterator.WIND_EVEN_ODD, PathIterator.WIND_NON_ZERO, PathIterator.getWindingRule()

isDone

public boolean isDone()

Tests if there are more points to read.

Specified by:

isDone in interface java.awt.geom.PathIterator

Returns:

true if there are more points to read

See Also:

PathIterator.isDone()

next

public void next()

Moves the iterator to the next segment of the path forwards along the primary direction of traversal as long as there are more points in that direction.

Specified by:

next in interface java.awt.geom.PathIterator

PathIterator.next()
