Examples with DbRowOp org.apache.cayenne.access.flush.operation.DbRowOp used on opensource projects

Example 1 with DbRowOp

use of org.apache.cayenne.access.flush.operation.DbRowOp in project cayenne by apache.

the class DbRowOpFactory method createRows.

Collection<? extends DbRowOp> createRows(ObjectDiff diff) {
    updateDiff(diff);
    DbEntity rootEntity = descriptor.getEntity().getDbEntity();
    DbRowOp row = getOrCreate(rootEntity, object.getObjectId(), DbRowOpType.forObject(object));
    rootRowOpProcessor.setDiff(diff);

Example 2 with DbRowOp

use of org.apache.cayenne.access.flush.operation.DbRowOp 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}
 */

    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
