Method Detail

getWindingRule

public int getWindingRule()

Description copied from interface: PathIterator

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

Specified by:

getWindingRule in interface PathIterator

Returns:

the winding rule.

PathIterator.WIND_EVEN_ODD, PathIterator.WIND_NON_ZERO

isDone

public boolean isDone()

Description copied from interface: PathIterator

Tests if the iteration is complete.

Specified by:

isDone in interface PathIterator

Returns:

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

next

public void next()

Description copied from interface: PathIterator

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 PathIterator

currentSegment

public int currentSegment(float[] coords)

Description copied from interface: PathIterator

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.

Specified by:

currentSegment in interface PathIterator

Parameters:

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

Returns:

the path-segment type of the current path segment.

PathIterator.SEG_MOVETO, PathIterator.SEG_LINETO, PathIterator.SEG_QUADTO, PathIterator.SEG_CUBICTO, PathIterator.SEG_CLOSE

currentSegment

public int currentSegment(double[] coords)

Description copied from interface: PathIterator

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 can 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 returns one point, SEG_QUADTO returns two points, SEG_CUBICTO returns 3 points and SEG_CLOSE does not return any points.

Specified by:

currentSegment in interface PathIterator

Parameters:

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

Returns:

the path-segment type of the current path segment.
