Example 1 with NodeCommand

use of org.neo4j.kernel.impl.transaction.command.Command.NodeCommand in project neo4j by neo4j.

the class BatchingTransactionAppenderTest method singleCreateNodeCommand.

private Collection<StorageCommand> singleCreateNodeCommand(long id) {
    Collection<StorageCommand> commands = new ArrayList<>();
    NodeRecord before = new NodeRecord(id);
    NodeRecord after = new NodeRecord(id);
    after.setInUse(true);
    commands.add(new NodeCommand(before, after));
    return commands;
}

Example 2 with NodeCommand

use of org.neo4j.kernel.impl.transaction.command.Command.NodeCommand in project neo4j by neo4j.

the class ApplyRecoveredTransactionsTest method shouldSetCorrectHighIdWhenApplyingExternalTransactions.

@Test
public void shouldSetCorrectHighIdWhenApplyingExternalTransactions() throws Exception {
    // WHEN recovering a transaction that creates some data
    long nodeId = neoStores.getNodeStore().nextId();
    long relationshipId = neoStores.getRelationshipStore().nextId();
    int type = 1;
    applyExternalTransaction(1, new NodeCommand(new NodeRecord(nodeId), inUse(created(new NodeRecord(nodeId)))), new RelationshipCommand(null, inUse(created(with(new RelationshipRecord(relationshipId), nodeId, nodeId, type)))));
    // and when, later on, recovering a transaction deleting some of those
    applyExternalTransaction(2, new NodeCommand(inUse(created(new NodeRecord(nodeId))), new NodeRecord(nodeId)), new RelationshipCommand(null, new RelationshipRecord(relationshipId)));
    // THEN that should be possible and the high ids should be correct, i.e. highest applied + 1
    assertEquals(nodeId + 1, neoStores.getNodeStore().getHighId());
    assertEquals(relationshipId + 1, neoStores.getRelationshipStore().getHighId());
}
