Constructor Summary |
Area.AreaIterator(AffineTransform at)
The contructor here does most of the work,
creates a vector of IteratorSegments, which can
readily be returned |

currentSegment
public int currentSegment(double[] coords)
- Description copied from interface:
PathIterator
- Returns the coordinates of the next point(s), as well as the type of
line segment. The input array must be at least a double[6], to accomodate
up to three (x,y) point pairs (although if you know the iterator is
flat, you can probably get by with a double[2]). If the returned type is
SEG_MOVETO or SEG_LINETO, the first point in the array is modified; if
the returned type is SEG_QUADTO, the first two points are modified; if
the returned type is SEG_CUBICTO, all three points are modified; and if
the returned type is SEG_CLOSE, the array is untouched.
- Specified by:
currentSegment in interface PathIterator
currentSegment
public int currentSegment(float[] coords)
- Description copied from interface:
PathIterator
- Returns the coordinates of the next point(s), as well as the type of
line segment. The input array must be at least a float[6], to accomodate

getWindingRule
public int getWindingRule()
- Description copied from interface:
PathIterator
- Returns the winding rule to determine which points are inside this path.
- Specified by:
getWindingRule in interface PathIterator
isDone
public boolean isDone()
- Description copied from interface:
PathIterator
- Tests if the iterator is exhausted. If this returns true, currentSegment
and next may throw a NoSuchElementException (although this is not
required).
- Specified by:
isDone in interface PathIterator
next
public void next()
- Description copied from interface:
PathIterator
- Advance to the next segment in the iteration. It is not specified what
this does if called when isDone() returns true.
- Specified by:
next in interface PathIterator
