Class Overview

Base class for enqueuing rendering operations in a single-threaded rendering environment. Instead of each operation being rendered immediately by the underlying graphics library, the operation will be added to the provided RenderQueue, which will be processed at a later time by a single thread. This class provides implementations of drawLine(), drawRect(), drawPoly(), fillRect(), draw(Shape), and fill(Shape), which are useful for a hardware-accelerated renderer. The other draw*() and fill*() methods simply delegate to draw(Shape) and fill(Shape), respectively.

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.
