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?
• finish

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

Method Summary

void	errors(Iterable<? extends Neo4jError> errors) Will get called once if any errors occurred, after statementResults has been called This method is not allowed to throw exceptions.
void	finish() This method must be called exactly once, and no method must be called after calling this method.
void	statementResult(org.neo4j.cypher.javacompat.ExecutionResult result) Will get called at most once per statement.

Method Detail

transactionCommitUri

public void transactionCommitUri(URI commitUri)

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.

IOException

errors

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