Class ExecutionResultSerializer

java.lang.Object

org.neo4j.server.rest.transactional.ExecutionResultSerializer

public class ExecutionResultSerializer
extends Object

Writes directly to an output stream, therefore implicitly stateful. Methods must be invoked in the correct order, as follows:

• transactionId?
• statementResult*
• errors?
• transactionStatus(long expiryDate)?
• finish

Where ? means invoke at most once, and * means invoke zero or more times.

Will always get called at most once once, and is the first method to get called. This method is not allowed to throw exceptions. If there are network errors or similar, the handler should take appropriate action, but never fail this method.

statementResult

public void statementResult(org.neo4j.graphdb.Result result,
                   boolean includeStats,
                   ResultDataContent... resultDataContents)
                     throws IOException

Will get called at most once per statement. Throws IOException so that upstream executor can decide whether to execute further statements.

Throws:

IOException

errors

public void errors(Iterable<? extends Neo4jError> errors)

Will get called once if any errors occurred, after statementResult(org.neo4j.graphdb.Result, boolean, ResultDataContent...) statementResults} has been called This method is not allowed to throw exceptions. If there are network errors or similar, the handler should take appropriate action, but never fail this method.
