Examples of FontUse

org.axsl.font.FontUse
The FontUse interface exposes a font resource to the client application. It encapsulates a {@link Font} as it is used by a specific{@link FontConsumer}, for a specific {@link Encoding} and for a specificfont family. It is possible for a {@link FontConsumer} to use the same{@link Font} instance in more than one way, due to more than one encoding orthe font being configured in more than one font family.
