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

Example 1 with ObjectStore

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

the class DataContextFactory method createFromDataContext.

protected ObjectContext createFromDataContext(DataContext parent) {
    // child ObjectStore should not have direct access to snapshot cache, so do not
    // pass it in constructor.
    ObjectStore objectStore = objectStoreFactory.createObjectStore(null);
    DataContext context = newInstance(parent, objectStore);
    context.setValidatingObjectsOnCommit(parent.isValidatingObjectsOnCommit());
    context.setUsingSharedSnapshotCache(parent.isUsingSharedSnapshotCache());
    context.setQueryCache(new NestedQueryCache(queryCache));
    context.setTransactionFactory(transactionFactory);
    return context;
}

Example 2 with ObjectStore

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

the class DefaultDataDomainFlushAction method flush.

@Override
public GraphDiff flush(DataContext context, GraphDiff changes) {
    CompoundDiff afterCommitDiff = new CompoundDiff();
    if (changes == null) {
        return afterCommitDiff;
    }
    if (!(changes instanceof ObjectStoreGraphDiff)) {
        throw new CayenneRuntimeException("Instance of ObjectStoreGraphDiff expected, got %s", changes.getClass());
    }
    ObjectStore objectStore = context.getObjectStore();

    List<DbRowOp> dbRowOps = createDbRowOps(objectStore, objectStoreGraphDiff);
    updateObjectIds(dbRowOps);
    List<DbRowOp> deduplicatedOps = mergeSameObjectIds(dbRowOps);

    List<DbRowOp> sortedOps = sort(filteredOps);
    List<? extends Query> queries = createQueries(sortedOps);
    executeQueries(queries);
    createReplacementIds(objectStore, afterCommitDiff, sortedOps);
    postprocess(context, objectStoreGraphDiff, afterCommitDiff, sortedOps);
    return afterCommitDiff;
}

Example 3 with ObjectStore

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

the class DefaultDataDomainFlushAction method postprocess.

/**
 * Notify {@link ObjectStore} and it's data row cache about actual changes we performed.
 *
 * @param context originating context
 * @param changes incoming diff
 * @param afterCommitDiff resulting diff
 * @param dbRowOps collection of {@link DbRowOp}
 */

    indirectDiffBuilder.processChanges(changes);
    objectStore.getDataRowCache().processSnapshotChanges(objectStore, postprocessor.getUpdatedSnapshots(), postprocessor.getDeletedIds(), Collections.emptyList(), indirectDiffBuilder.getIndirectModifications());
    objectStore.postprocessAfterCommit(afterCommitDiff);
}
