java.lang.Objectorg.eclipse.emf.ecore.resource.impl.CryptoCipherImpl
EMF default implementation for the URIConverter.Cipher
interface.
This is an example of how this class can be used:
Map options = new HashMap(); options.put(Resource.OPTION_CIPHER, new CryptoCipherImpl("a very long key indeed")); resource.save(options); resource.load(options);
