All Implemented Interfaces:

ErrorConstants, RegistryEntry, StreamRegistryEntry

Direct Known Subclasses:

ImageIOJPEGRegistryEntry, ImageIOPNGRegistryEntry, ImageIOTIFFRegistryEntry

public abstract class AbstractImageIORegistryEntry
extends MagicNumberRegistryEntry

This is the base class for all ImageIO-based RegistryEntry implementations. They have a slightly lower priority than the RegistryEntry implementations using the internal codecs, so these take precedence if they are available.
