Method Detail

nodesGetForLabel

org.neo4j.kernel.impl.api.PrimitiveLongIterator nodesGetForLabel(Statement state,
                                                               long labelId)

Parameters:: labelId - the label id of the label that returned nodes are guaranteed to have
Returns:: ids of all nodes that have the given label

nodesGetFromIndexLookup

org.neo4j.kernel.impl.api.PrimitiveLongIterator nodesGetFromIndexLookup(Statement state,
                                                                      org.neo4j.kernel.impl.api.index.IndexDescriptor index,
                                                                      Object value)
                                                                        throws IndexNotFoundKernelException

Returns an iterable with the matched nodes.

Throws:: IndexNotFoundKernelException - if no such index found.

nodeHasLabel
```
boolean nodeHasLabel(Statement state,
                   long nodeId,
                   long labelId)
                     throws EntityNotFoundException
```
Checks if a node is labeled with a certain label or not. Returns true if the node is labeled with the label, otherwise false. Label ids are retrieved from KeyWriteOperations.labelGetOrCreateForName(org.neo4j.kernel.api.Statement, String) or KeyReadOperations.labelGetForName(org.neo4j.kernel.api.Statement, String).

Throws:

EntityNotFoundException

nodeGetLabels
