                            org.neo4j.kernel.impl.api.constraints.ConstraintValidationKernelException

Description copied from interface: EntityWriteOperations

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).
