Interface ILfnDeleteTileHandler

All Superinterfaces:

ILfnFailureHandler, ILfnServiceFailureHandler

public interface ILfnDeleteTileHandler
extends ILfnServiceFailureHandler

A handler for asynchronous tile deletion operations. Tile deletions are transactions.

Unless canceled, there will always be a single interaction with the handler. Exactly one of the methods will be called, indicating that the associated request has been handled, or failed/interrupted.

Method Details

deleted

void deleted(long aTransactionManagementId,
 long aSequentialTransactionId,
 long aHighestCommittedTransactionId)

Indicates that the tile was deleted from the Tile Store, and provides a unique transaction ID for this tile deletion. The tile is deleted but not yet committed.

A tile deletion transaction ID consists of two parts:

1. transaction management ID
2. sequential transaction ID

The combination of the two will result in a unique transaction ID.

The transaction management ID is normally fixed and only changes in failure scenarios. If the client has outstanding transactions with a different management ID, it has to discard its transactions and possibly retry them.

The sequential transaction ID is a strictly increasing number. The highest committed transaction ID indicates that all outstanding transactions of the same management ID and a lower or equal transaction ID have been committed.

Parameters:

aTransactionManagementId - the unique transaction management ID

aSequentialTransactionId - the sequential transaction ID for this particular request

aHighestCommittedTransactionId - the highest committed transaction ID

notFound

void notFound()

Indicates that the tile was not found in the Tile Store. Note that since no tile was found, there is no transaction either.
