Examples with Persistent org.apache.cayenne.Persistent used on opensource projects

Example 1 with Persistent

use of org.apache.cayenne.Persistent in project cayenne by apache.

the class DataDomainFlushAction method preprocess.

private void preprocess(DataContext context, GraphDiff changes) {
    // categorize dirty objects by state
    ObjectStore objectStore = context.getObjectStore();
    for (Object o : changesByObjectId.keySet()) {
        ObjectId id = (ObjectId) o;
        Persistent object = (Persistent) objectStore.getNode(id);
        ClassDescriptor descriptor = context.getEntityResolver().getClassDescriptor(id.getEntityName());
        switch(object.getPersistenceState()) {
            case PersistenceState.NEW:
                insertBucket.addDirtyObject(object, descriptor);

        }
    }
    new DataDomainIndirectDiffBuilder(this).processIndirectChanges(changes);
    insertBucket.appendQueries(queries);
    // TODO: the following line depends on the "queries" collection filled by insertBucket.. Moreover it may
    // potentially remove values from the passed collection. Replace with something with fewer unobvious
    // side-effects...
