java.lang.Object java.awt.RenderingHints.Key
public abstract static class RenderingHints.Key
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.
