The TaskListMigrator and TaskListFactory are exclusive. Here are some notes I
made while porting the web connector:
In Mylyn 3.0 the data model of the task list has changed. Elements in the task
list are now managed by the tasks framework and connectors do not extend
AbstractTask or AbstractRepositoryQuery with their own implementation. Task
list externalization that previously required connectors to provide an
implementation of AbstractTaskListFactory is now encapsulated in the
framework.
In order to migrate the Mylyn 2.x tasklist.xml.zip to the new tasks.xml.zip
file connectors need to extend AbstractTaskListMigrator. When a Mylyn 2.x
task list is read the migrator is invoked for migrating query and tasks
elements. The migration is only done once.
The task list migrator is registered through the
org.eclipse.mylyn.tasks.ui.repositories extension point. The taskListFactory
element is replaced by taskListMigrator:
<extension
id="org.eclipse.mylyn.web.repository"
name="Generic web-based access (Advanced)"
point="org.eclipse.mylyn.tasks.ui.repositories">
<connectorCore ... />
<connectorUi ... />
<taskListMigrator
class="org.eclipse.mylyn.internal.web.tasks.WebTaskListMigrator">
</taskListMigrator>
</extension>
The implementating of AbstractTaskListFactory.createTask() moved to
AbstractTaskListMigrator.migrateTask(). Instead of creating an instance of a
custom task class connector set custom state on task classes through the
setAttribute() method:
WebTaskListMigrator {
@Override
public void migrateTask(ITask task, Element element) {
if (element.hasAttribute(KEY_PREFIX)) {
task.setAttribute(WebRepositoryConnector.KEY_TASK_PREFIX,
element.getAttribute(KEY_PREFIX));
}
}
In addition connectors must migrate the last read time stamp (see
JiraTaskListMigrator).
Connectors that used to override AbstractTask.getTaskKey() need to explicitly
set the task key during mirgration. It is initialized to the task id by
default (see JiraTaskListMigrator).
Connectors that used to override AbstractTask.isLocal() should now implement
AbstractRepositoryConnector.hasLocalCompletionState() (see
WebRepositoryConnector).
We are in the process of assembling bits and pieces of documentation. Please
feel free to ask if you have any further questions.
