public abstract static class RenderingHints.Key extends Object
Defines the base type of all keys used along with the {@link 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 {@code ==} operator instead of the more expensive {@code equals()} method.
