Method Detail

afterChunk

public void afterChunk(ChunkContext context)

Description copied from interface: ChunkListener

Callback after the chunk is executed, outside the transaction.

Specified by:

afterChunk in interface ChunkListener

Parameters:

context - The current ChunkContext

beforeChunk

public void beforeChunk(ChunkContext context)

Description copied from interface: ChunkListener

Callback before the chunk is executed, but inside the transaction.

Specified by:

beforeChunk in interface ChunkListener

Parameters:

context - The current ChunkContext

afterChunkError

public void afterChunkError(ChunkContext context)

Description copied from interface: ChunkListener

Callback after a chunk has been marked for rollback. It is invoked after transaction rollback. While the rollback will have occurred, transactional resources might still be active and accessible. Due to this, data access code within this callback will still "participate" in the original transaction unless it declares that it run in its own transaction. Hence: Use PROPAGATION_REQUIRES_NEW for any transactional operation that is called from here.

Specified by:

afterChunkError in interface ChunkListener

Parameters:

context - the chunk context containing the exception that caused the underlying rollback.
