Interface BatchTransactionContextFactory

All Known Implementing Classes:

DefaultBatchTransactionContextFactory

public interface BatchTransactionContextFactory

Factory class for instances of BatchTransactionContext It keeps track of the created contexts so that upon mule shutdown, any transactions still active (meaning, transactions that still hasn't been rolled back or committed) are rolled back automatically to prevent data loss. Implementations of this interface have to be thread safe

Since:

3.5.0

Method Summary

Modifier and Type	Method and Description
void	closeAndRollback() closes this factory meaning that it will not accept requests to create any addiitional BatchTransactionContexts.
int	countOpenTransactions() For monitoring and testing purposes only
BatchTransactionContext	createTransactionContext(BatchJobInstanceAdapter jobInstance) Creates and tracks a new BatchTransactionContext associated to the given BatchJobInstanceAdapter

Method Detail

createTransactionContext

BatchTransactionContext createTransactionContext(BatchJobInstanceAdapter jobInstance)

Creates and tracks a new BatchTransactionContext associated to the given BatchJobInstanceAdapter

Parameters:

jobInstance - a not null BatchJobInstanceAdapter

Returns:

a new BatchTransactionContext

Throws:

IllegalStateException - if invoked after closeAndRollback() was invoked

closeAndRollback

void closeAndRollback()

closes this factory meaning that it will not accept requests to create any addiitional BatchTransactionContexts. If createTransactionContext(com.mulesoft.mule.runtime.module.batch.engine.BatchJobInstanceAdapter) is invoked after this method it will throw IllegalStateException. Any active transactions that hasn't been rolled back or commit at the moment of invoking this method will be automatically rolled back. This method is thread safe and can be safely invoked multiple times

countOpenTransactions

int countOpenTransactions()

For monitoring and testing purposes only

Returns:

how many BatchTransactionContext instances have been created but not closed yet
