org.activiti.engine.impl.variable.VerifyDeserializedObjectCommandContextCloseListener

All Implemented Interfaces:

CommandContextCloseListener

public class VerifyDeserializedObjectCommandContextCloseListener
extends Object
implements CommandContextCloseListener

A CommandContextCloseListener that holds one DeserializedObject instance that is added by the SerializableType. On the closing(CommandContext) of the CommandContext, the DeserializedObject will be verified if it is dirty. If so, it will update the right entities such that changes will be flushed. It's important that this happens in the closing(CommandContext), as this happens before the CommandContext.close() is called and when all the sessions are flushed (including the DbSqlSession in the relational DB case (the data needs to be ready then).

Method Details

closing

public void closing(CommandContext commandContext)

Description copied from interface: CommandContextCloseListener

Called when the CommandContext is being closed, but no 'close logic' has been executed. At this point, the TransactionContext (if applicable) has not yet been committed/rolledback and none of the Session instances have been flushed. If an exception happens and it is not caught in this method: - The Session instances will *not* be flushed - The TransactionContext will be rolled back (if applicable)

Specified by:

closing in interface CommandContextCloseListener

closed

public void closed(CommandContext commandContext)

Description copied from interface: CommandContextCloseListener

Called when the CommandContext is successfully closed. At this point, the TransactionContext (if applicable) has been successfully committed and no rollback has happened. All Session instances have been closed. Note that throwing an exception here does *not* affect the transaction. The CommandContext will log the exception though.

Specified by:

afterSessionsFlush

public void afterSessionsFlush(CommandContext commandContext)

Description copied from interface: CommandContextCloseListener

Called when the Session have been successfully flushed. When an exception happened during the flushing of the sessions, this method will not be called. If an exception happens and it is not caught in this method: - The Session instances will *not* be flushed - The TransactionContext will be rolled back (if applicable)

Specified by:

closeFailure

public void closeFailure(CommandContext commandContext)

Description copied from interface: CommandContextCloseListener

Called when the CommandContext has not been successully closed due to an exception that happened. Note that throwing an exception here does *not* affect the transaction. The CommandContext will log the exception though.
