Example 1 with NodeProxy

use of org.neo4j.kernel.impl.core.NodeProxy in project neo4j by neo4j.

the class GraphDatabaseFacade method init.

/**
     * Create a new Core API facade, backed by the given SPI and using pre-resolved dependencies
     */
public void init(SPI spi, Guard guard, ThreadToStatementContextBridge txBridge, Config config) {
    this.spi = spi;

}

Example 2 with NodeProxy

use of org.neo4j.kernel.impl.core.NodeProxy in project neo4j by neo4j.

the class GraphDatabaseFacade method allNodesWithLabel.

private ResourceIterator<Node> allNodesWithLabel(final Label myLabel) {
    Statement statement = spi.currentStatement();
    int labelId = statement.readOperations().labelGetForName(myLabel.name());
    if (labelId == KeyReadOperations.NO_SUCH_LABEL) {
        statement.close();
        return emptyIterator();
    }
    final PrimitiveLongIterator nodeIds = statement.readOperations().nodesGetForLabel(labelId);
    return ResourceClosingIterator.newResourceIterator(statement, map(nodeId -> new NodeProxy(nodeActions, nodeId), nodeIds));
