Examples of javax.tools.diagnostics.FactoryRegistry

javax.tools.diagnostics.FactoryRegistry
Experimental addition to the API.
This class provides a central registry for image factories
Image factories can be registered directly using the {@link #addFactory()} method.
The default registry obtained by calling {@link #getDefaultRegistry()} uses {@link javax.imageio.spi.ServiceRegistry} to discoverImageFactory implementations.
To register an ImageFactory implementation that can be discovered by the registry do the following :
- Create a 'services' directory as a child of the manfest directory 'META-INF'
- Within this 'services' directory create a text file called 'javax.tools.diagnostics.image.ImageFactory'
- This text file should contain a single line which is the package qualified name of the ImageFactory implementation to be registered
