Example 66 with RelationshipRecord

use of org.neo4j.kernel.impl.store.record.RelationshipRecord in project neo4j by neo4j.

the class ApplyRecoveredTransactionsTest method shouldSetCorrectHighIdWhenApplyingExternalTransactions.

    applyExternalTransaction(2, new NodeCommand(inUse(created(new NodeRecord(nodeId))), new NodeRecord(nodeId)), new RelationshipCommand(null, new RelationshipRecord(relationshipId)));
