Class Transaction

java.lang.Object
  net.sourceforge.fluxion.runcible.io.command.Transaction

public class Transaction
extends java.lang.Object

A Transaction is a group of commands, which must be in some way associated. This way, the commands are executed as they are submitted to the ChangeInvoker, but composed into a grouping, so that when a transaction is closed, the commands within this transaction are compiled into a single CompositeCommand. Consequently, commands submitted as part of a transaction are executed as normal, and undone as normal, until the transaction is closed, at which point an undo call undoes all the commands in the transaction.
