Method Detail

getSingleNode

public static org.neo4j.graphdb.Node getSingleNode(org.neo4j.graphdb.ResourceIterable<org.neo4j.graphdb.Node> iterable)

Returns the only node contained in iterable or null, if no such node exists. If the iterable contains more than one node, an exception will be thrown.

Parameters:

iterable -

Returns:

The only node in iterable or null if there is no node.

Throws:

IllegalStateException - If iterable contains more than one node.

getSingleNode

public static org.neo4j.graphdb.Node getSingleNode(org.neo4j.graphdb.ResourceIterator<org.neo4j.graphdb.Node> iterator)

findSingleNodeByLabelAndProperty

public static org.neo4j.graphdb.Node findSingleNodeByLabelAndProperty(org.neo4j.graphdb.GraphDatabaseService graphDb,
                                                                      org.neo4j.graphdb.Label label,
                                                                      String key,

getSingleOtherNode

public static org.neo4j.graphdb.Node getSingleOtherNode(org.neo4j.graphdb.Node node,
                                                        org.neo4j.graphdb.RelationshipType type)

copyNode

public static org.neo4j.graphdb.Node copyNode(org.neo4j.graphdb.GraphDatabaseService graphDb,

getNodePropertyAsStringArrayValue

public static String[] getNodePropertyAsStringArrayValue(org.neo4j.graphdb.Node node,
                                                         String property)

Gets the string or string array value of property from node. Always returns an array. If the value is a single string, it will be returned as array of size one, containing only this value.

Parameters:

node -

property -

Returns:
