Examples with ObjectDiff org.apache.cayenne.access.ObjectDiff used on opensource projects

Example 1 with ObjectDiff

use of org.apache.cayenne.access.ObjectDiff in project cayenne by apache.

the class DefaultDataDomainFlushAction method createDbRowOps.

/**
 * Create ops based on incoming graph changes
 * @param objectStore originating object store
 * @param changes object graph diff
 * @return collection of {@link DbRowOp}
 */
protected List<DbRowOp> createDbRowOps(ObjectStore objectStore, ObjectStoreGraphDiff changes) {
    EntityResolver resolver = dataDomain.getEntityResolver();
    Map<Object, ObjectDiff> changesByObjectId = changes.getChangesByObjectId();
    List<DbRowOp> ops = new ArrayList<>(changesByObjectId.size());
    Set<ArcTarget> processedArcs = new HashSet<>();
    DbRowOpFactory factory = new DbRowOpFactory(resolver, objectStore, processedArcs);
    // ops.addAll() method is slower in this case as it will allocate new array for all values
    // noinspection UseBulkOperation
    changesByObjectId.forEach((obj, diff) -> factory.createRows(diff).forEach(ops::add));
    return ops;
}
