List of coverage <A HREF="../../../../../org/geotools/coverage/processing/AbstractOperation.html" title="class in org.geotools.coverage.processing">operations</A>.
    This package is useful for documentation purpose since class names match exactly operation
    names, and the javadoc for each class provides a table of valid arguments. But the classes
    provided there should not be used directly. There is no need to instantiate them, since it
    is already done by the <A HREF="../../../../../org/geotools/coverage/processing/DefaultProcessor.html" title="class in org.geotools.coverage.processing">processor</A>
    which manage them.
