Method Detail

state

public org.neo4j.bolt.v1.runtime.TransactionStateMachine.State state()

run

public org.neo4j.bolt.v1.runtime.StatementMetadata run(String statement,
                                                       Map<String,Object> params)
                                                throws org.neo4j.kernel.api.exceptions.KernelException

Specified by:

run in interface StatementProcessor

Throws:

org.neo4j.kernel.api.exceptions.KernelException

streamResult

public void streamResult(org.neo4j.function.ThrowingConsumer<BoltResult,Exception> resultConsumer)
                  throws Exception

Specified by:

streamResult in interface StatementProcessor

Throws:

Exception

reset

public void reset()
           throws org.neo4j.kernel.api.exceptions.TransactionFailureException

Rollback and close transaction. Move back to State#AUTO_COMMIT.

Warning:This method should only be called by the bolt worker thread during it's regular message processing. It is wrong to call it from a different thread because kernel transactions are not thread-safe.

Specified by:

reset in interface StatementProcessor

Throws:

org.neo4j.kernel.api.exceptions.TransactionFailureException - when transaction fails to close.
