Defines the base type of all keys used along with the
RenderingHints
class to control various
algorithm choices in the rendering and imaging pipelines.
Instances of this class are immutable and unique which
means that tests for matches can be made using the
==
operator instead of the more expensive
equals()
method.

From class
java.lang.Object
|
Construct a key using the indicated private key. Each subclass of Key maintains its own unique domain of integer keys. No two objects with the same integer key and of the same specific subclass can be constructed. An exception will be thrown if an attempt is made to construct another object of a given class with the same integer key as a pre-existing instance of that subclass of Key.

true
if this object is the same as the obj

otherwise.The hash code for all Key objects will be the same as the system identity code of the object as defined by the System.identityHashCode() method.
Returns true if the specified object is a valid value for this Key.
val | the Object to test for validity |

is valid;

otherwise.
Returns the private integer key that the subclass instantiated this Key with.
