Interface Batch

All Known Implementing Classes:
AbstractBatchImpl, BatchedManyToManyTest.TestingBatch, BatchingBatch, InsertOrderingTest.StatsBatch, NonBatchingBatch

public interface Batch

Conceptually models a batch.

Unlike directly in JDBC, here we add the ability to batch together multiple statements at a time. In the underlying JDBC this correlates to multiple PreparedStatement objects (one for each DML string) maintained within the batch.


Method Summary
 void addObserver(BatchObserver observer)
          Adds an observer to this batch.
 void addToBatch()
          Indicates completion of the current part of the batch.
 void execute()
          Execute this batch.
 PreparedStatement getBatchStatement(String sql, boolean callable)
          Get a statement which is part of the batch, creating if necessary (and storing for next time).
 BatchKey getKey()
          Retrieves the object being used to key (uniquely identify) this batch.
 void release()
          Used to indicate that the batch instance is no longer needed and that, therefore, it can release its resources.
 

Method Detail

getKey

BatchKey getKey()
Retrieves the object being used to key (uniquely identify) this batch.

Returns:
The batch key.

addObserver

void addObserver(BatchObserver observer)
Adds an observer to this batch.

Parameters:
observer - The batch observer.

getBatchStatement

PreparedStatement getBatchStatement(String sql,
                                    boolean callable)
Get a statement which is part of the batch, creating if necessary (and storing for next time).

Parameters:
sql - The SQL statement.
callable - Is the SQL statement callable?
Returns:
The prepared statement instance, representing the SQL statement.

addToBatch

void addToBatch()
Indicates completion of the current part of the batch.


execute

void execute()
Execute this batch.


release

void release()
Used to indicate that the batch instance is no longer needed and that, therefore, it can release its resources.
