Examples with CloseableIterable org.apache.jackrabbit.oak.plugins.document.util.CloseableIterable used on opensource projects

Example 1 with CloseableIterable

use of org.apache.jackrabbit.oak.plugins.document.util.CloseableIterable in project jackrabbit-oak by apache.

the class MongoDocumentTraverser method getAllDocuments.

public <T extends Document> CloseableIterable<T> getAllDocuments(Collection<T> collection, Predicate<String> filter) {
    if (!disableReadOnlyCheck) {
        checkState(mongoStore.isReadOnly(), "Traverser can only be used with readOnly store");
    }
    MongoCollection<BasicDBObject> dbCollection = mongoStore.getDBCollection(collection);
    // TODO This may lead to reads being routed to secondary depending on MongoURI
    // So caller must ensure that its safe to read from secondary
    Iterable<BasicDBObject> cursor = dbCollection.withReadPreference(mongoStore.getConfiguredReadPreference(collection)).find();
    CloseableIterable<BasicDBObject> closeableCursor = CloseableIterable.wrap(cursor);
    cursor = closeableCursor;
    @SuppressWarnings("Guava") Iterable<T> result = FluentIterable.from(cursor).filter(o -> filter.test((String) o.get(Document.ID))).transform(o -> {
        T doc = mongoStore.convertFromDBObject(collection, o);
        // TODO Review the cache update approach where tracker has to track *all* docs
        if (collection == Collection.NODES) {
            NodeDocument nodeDoc = (NodeDocument) doc;
            getNodeDocCache().put(nodeDoc);
        }
        return doc;
    });
    return CloseableIterable.wrap(result, closeableCursor);
}
