Method Detail

getWindingRule

public int getWindingRule()

Returns the winding rule for determining the interior of the path.

isDone

public boolean isDone()

Tests if the iteration is complete.

Returns:

true if all the segments have been read; false otherwise.

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.

currentSegment

public int currentSegment(PathIteratorHelper.Struct struct)

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 float array of length 6 must be passed in and can be used to store the coordinates of the point(s). Each point is stored as a pair of float x,y coordinates. SEG_MOVETO and SEG_LINETO types returns one point, SEG_QUADTO returns two points, SEG_CUBICTO returns 3 points and SEG_CLOSE does not return any points.

Parameters:

coords - an array that holds the data returned from this method

Returns:

the path-segment type of the current path segment.
