Method Detail

nodeDelete

void nodeDelete(Statement state,
              long nodeId)

relationshipDelete

void relationshipDelete(Statement state,
                      long relationshipId)

nodeAddLabel

boolean nodeAddLabel(Statement state,
                   long nodeId,
                   long labelId)
                     throws EntityNotFoundException,
                            org.neo4j.kernel.impl.api.constraints.ConstraintValidationKernelException

Labels a node with the label corresponding to the given label id. If the node already had that label nothing will happen. Label ids are retrieved from KeyWriteOperations.labelGetOrCreateForName(org.neo4j.kernel.api.Statement, String) or KeyReadOperations.labelGetForName(org.neo4j.kernel.api.Statement, String).

Throws:

EntityNotFoundException
