Example 1 with ProxyModelMergeDelegate

use of org.apache.cayenne.dbsync.reverse.dbload.ProxyModelMergeDelegate in project cayenne by apache.

the class DefaultDbImportAction method applyTokens.

private boolean applyTokens(DataMap targetDataMap, Collection<MergerToken> tokens, DbImportConfiguration config) {
    if (tokens.isEmpty()) {
        logger.info("");
        logger.info("Detected changes: No changes to import.");
        return false;
    }
    final Collection<ObjEntity> loadedObjEntities = new LinkedList<>();
    ModelMergeDelegate mergeDelegate = new ProxyModelMergeDelegate(config.createMergeDelegate()) {

        @Override
        public void objEntityAdded(ObjEntity ent) {
            loadedObjEntities.add(ent);

    ObjectNameGenerator nameGenerator = config.createNameGenerator();
    MergerContext mergerContext = MergerContext.builder(targetDataMap).delegate(mergeDelegate).nameGenerator(nameGenerator).usingPrimitives(config.isUsePrimitives()).usingJava7Types(config.isUseJava7Types()).meaningfulPKFilter(config.createMeaningfulPKFilter()).build();
    for (MergerToken token : tokens) {

        } catch (Throwable th) {
            String message = "Migration Error. Can't apply changes from token: " + token.getTokenName() + " (" + token.getTokenValue() + ")";
            logger.error(message, th);
            mergerContext.getValidationResult().addFailure(new SimpleValidationFailure(th, message));
        }
    }

    return new ProxyModelMergeDelegate(new DefaultModelMergeDelegate()) {

        @Override
        public void objEntityAdded(ObjEntity ent) {

            super.objEntityAdded(ent);
        }
