Examples with NodeResultStream org.structr.bolt.index.NodeResultStream used on opensource projects

Example 1 with NodeResultStream

use of org.structr.bolt.index.NodeResultStream in project structr by structr.

the class BoltDatabaseService method getNodesByLabel.

@Override
public QueryResult<Node> getNodesByLabel(final String type) {
    if (type == null) {
        return getAllNodes();
    }
    final StringBuilder buf = new StringBuilder();
    buf.append("MATCH (n");
    if (tenantId != null) {
        buf.append(":");
        buf.append(tenantId);
    }
    buf.append(":");
    buf.append(type);
    buf.append(") RETURN n");
    return QueryUtils.map(new NodeNodeMapper(this), new NodeResultStream(this, new SimpleCypherQuery(buf.toString())));
}

Example 2 with NodeResultStream
