A Transaction cloud is a cloud which buffers allc hanegs made to nodes - which means that chanegs are committed only if you commit the transaction itself. This mechanism allows you to rollback changes if something goes wrong. author:    Pierre van Rooden version:    $Id: BasicTransaction.java,v 1.36 2008/01/09 10:56:36 michiel Exp $ Field Summary protected  BasicCloud parentCloud      protected  String transactionContext      The id of the transaction for use with the transaction manager. protected  String transactionName      The name of the transaction as used by the user.

Constructor Detail BasicTransaction BasicTransaction(String transactionName, BasicCloud cloud)(Code) Method Detail add void add(String currentObjectContext)(Code) add int add(BasicNode node)(Code) cancel public synchronized void cancel()(Code) commit public synchronized boolean commit()(Code) contains boolean contains(MMObjectNode node)(Code) createAlias void createAlias(BasicNode node, String aliasName)(Code) delete void delete(String currentObjectContext, MMObjectNode node)(Code) delete void delete(String currentObjectContext)(Code) finalize protected void finalize()(Code) If this Transaction is scheduled to be garbage collected, the transaction is canceled and cleaned up. Unless it has already been committed/canceled, ofcourse, and unless the parentcloud of a transaction is a transaction itself. In that case, the parent transaction should cancel! This means that a transaction is always cleared - if it 'times out', or is not properly removed, it will eventually be removed from the MMBase cache. getCloudName public String getCloudName()(Code)
