> URL: https://issues.apache.org/jira/browse/DDLUTILS-215
> Project: DdlUtils
> Issue Type: Improvement
> Components: Core (No specific database)
> Affects Versions: 1.0
> Reporter: Rick Riemer
> Assignee: Thomas Dudziak
> Fix For: 1.1

> Attachments: add_custom_change_capability.patch

> The Platform interface allows for upgrading a database from one model to
> another using the getAlterModelSql() method. This method tries to
> automatically convert from one model to another. In some cases it may be
> useful to allow the caller to provide for the changes that should be
> processed instead of automatically determining the changes.
> I'm attaching a patch that makes the PlatformImplBase.processChanges() method
> available on the Platform interface, thereby allow the caller to apply a
> custom list of changes. Next to that, the patch introduces the CustomChange
> interface, through which the caller can define custom changes (e.g.:
> executing custom SQL statements).
> This patch may also fix #DDLUTILS-213
