RegionIterator

extends Object

java.lang.Object
↳	sun.java2d.pipe.RegionIterator

Class Overview

This class defines the API for iterating through the bands of a region object.

Summary

Public Methods
void	copyStateFrom(RegionIterator ri) Copies the iteration state from this RegionIterator object into another RegionIterator object to allow multiple iteration branches from the current position.
RegionIterator	createCopy() Returns a new RegionIterator object representing the same iteration state as this object to allow multiple iteration branches from the current position.
boolean	nextXBand(int[] range) Moves the iteration state to the beginning of the next X band in the current Y range returning true if one is found and recording the low and high X coordinates of the range in the array at locations 0 and 2 respectively.
boolean	nextYRange(int[] range) Moves the iteration state to the beginning of the next Y range in the region returning true if one is found and recording the low and high Y coordinates of the range in the array at locations 1 and 3 respectively.

Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Public Methods

public void copyStateFrom (RegionIterator ri)

Copies the iteration state from this RegionIterator object into another RegionIterator object to allow multiple iteration branches from the current position.

public RegionIterator createCopy ()

Returns a new RegionIterator object representing the same iteration state as this object to allow multiple iteration branches from the current position.

public boolean nextXBand (int[] range)

Moves the iteration state to the beginning of the next X band in the current Y range returning true if one is found and recording the low and high X coordinates of the range in the array at locations 0 and 2 respectively.

public boolean nextYRange (int[] range)

Moves the iteration state to the beginning of the next Y range in the region returning true if one is found and recording the low and high Y coordinates of the range in the array at locations 1 and 3 respectively.
