Re: [mylyn-integrators] how to get ITask object from task ID?
|
Just out of curiosity, what kind of connector are you working on?
i'm working on a StarTeam connector, it provides SDK (Java APIs) to access the server...
actually, i problem is the getTaskData signature only pass a String of Task ID, and TaskRepository object.
as this method supposed, i need retrieve the full task details from server
for web/http access system like JIRA, bugzilla, Trac, etc. it won't be a pb
since they all have a uniform query interface by TaskID
e.g. JIRA: http://hostname:port/TASKID
but for StarTeam, tasks/CRs are stored under the folder, so the pseudo-url:
hostname:port/Project/View/FolderA/FoderB/TASKID
currently, i put the "/Project/View/FolderA/FoderB/" part in IRespositoryQuery
go back to the getTaskData() method, i cannot retrieve the full task details since incomplete context info (nowhere to get the path part)
The getTaskData() method is indeed expected to return the full details
of a task. I would recommend encoding all relevant information
required to retrieve the task into the task id or store it on the
TaskRepository object if it's not specific to a task.
yep,
i'm also considering put some context info (e.g. path) to the
TaskRepository, which will be persisted into respository.xml.zip
and retrieve the context info via the TaskRespository attributes access methods...
but, you know, it's the last option
If that is not feasible you could consider overriding
AbstractRepositoryConnector.canSynchronizeTask() and return false. If
you ensure that performQuery() always returns non partial task data
you should still be able to leverage almost all functionality of the
framework. One limitation is that looking up repository tasks by id
will not work unless a task is already in the task list.
Oh? could it be a case that I handle a Task ID, which passed as a argument by mylyn framework, but the corresponding task not in the task list?
One more thing, i'm considering use TasksUiPlugin.getTaskList() to retrieve the task list, and query task by id/key with the methods provided by TaskList.
but one pb is TasksUiPlugin.getTaskList() depends on the Mylyn Task UI plugin, but my code (RespositoryConnector) actually lay in a Core plugin...
any suggestions?
Thanks & Best Regards!
