Examples with Diagnostic org.eclipse.emf.ecore.resource.Resource.Diagnostic used on opensource projects

Example 6 with Diagnostic

use of org.eclipse.emf.ecore.resource.Resource.Diagnostic in project smarthome by eclipse.

the class ModelRepositoryImpl method validateModel.

/**
 * Validates the given model.
 *
 * There are two "layers" of validation
 * <ol>
 * <li>
 * errors when loading the resource. Usually these are syntax violations which irritate the parser. They will be
 * returned as a String.
 * <li>
 * all kinds of other errors (i.e. violations of validation checks) will only be logged, but not included in the
 * return value.
 * </ol>
 * <p>
 * Validation will be done on a separate resource, in order to keep the original one intact in case its content
 * needs to be removed because of syntactical errors.
 *
 * @param name
 * @param inputStream
 * @return error messages as a String if any syntactical error were found, <code>null</code> otherwise
 * @throws IOException if there was an error with the given {@link InputStream}, loading the resource from there
