Interface ManagedResultSet

All Superinterfaces:

java.lang.AutoCloseable, java.sql.ResultSet, java.sql.Wrapper

public interface ManagedResultSet
extends java.sql.ResultSet

A managed result set extends a ResultSet by the means to handle remote iterator. This is closely coupled to a transaction managed by a TxManager.

Method Detail

registerRemoteIterator

void registerRemoteIterator(RemoteIterator<?> iterator,
                            long aliveTime)

Registers the designated remote iterator to drop it after the designated alive time has elapsed. The iterator can be safely dropped beforehand and signal this via remoteIteratorDropped(RemoteIterator).

Parameters:

iterator - The iterator to drop after its alive time has elapsed.

aliveTime - The time in milliseconds the designated iterator can be active without being forced to be dropped.

remoteIteratorDropped

void remoteIteratorDropped(RemoteIterator<?> iterator)

Signals the dropping of the remote iterator which may allow to close the corresponding transaction.

Parameters:

iterator - The remote iterator that has been dropped.

getStatement

ManagedStatement getStatement()
                       throws java.sql.SQLException

Specified by:

getStatement in interface java.sql.ResultSet

Throws:

java.sql.SQLException
