Public constructors
RegionIterator
RegionIterator(region: Region!)
Construct an iterator for all of the rectangles in a region. This effectively makes a private copy of the region, so any subsequent edits to region will not affect the iterator.
| Parameters |
region |
Region!: the region that will be iterated |
Public methods
next
fun next(r: Rect!): Boolean
Return the next rectangle in the region. If there are no more rectangles this returns false and r is unchanged. If there is at least one more, this returns true and r is set to that rectangle.
Protected methods
finalize
protected open fun finalize(): Unit
| Exceptions |
java.lang.Throwable |
the Exception raised by this method |
