Method Detail

getWindingRule

public int getWindingRule()

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

Specified by:

getWindingRule in interface PathIterator

Returns:

an integer representing the current winding rule.

See Also:

PathIterator.WIND_NON_ZERO

isDone

public boolean isDone()

Tests if there are more points to read.

Specified by:

isDone in interface PathIterator

Returns:

true if there are more points to read; false otherwise.

next

public void next()

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

Specified by:

next in interface 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, or SEG_CLOSE. A float array of length 2 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 return one point, and SEG_CLOSE does not return any points.

Specified by:

currentSegment in interface PathIterator

Parameters:

coords - a float array that specifies the coordinates of the point(s)

Returns:

an integer representing the type and coordinates of the current path segment.

See Also:

PathIterator.SEG_MOVETO, PathIterator.SEG_LINETO, PathIterator.SEG_CLOSE

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, or SEG_CLOSE. A double array of length 2 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 return one point, and SEG_CLOSE does not return any points.

Specified by:

currentSegment in interface PathIterator

Parameters:

coords - a double array that specifies the coordinates of the point(s)

Returns:

an integer representing the type and coordinates of the current path segment.
