[mylyn-dev] tips on efficent read access to Task attributes
|
Hi,
I'm writing a couple of grid-tree views to help understand and edit Jira
tasks, seen by Mylyn.
The grid has columns for some Jira attributes that are not part of the
ITask API
- JIRA Component, Fix Version, and a few custom JIRA fields.
Please can someone give me tips on how to efficienly access
TaskAttribute values that are not given by the ITask API.
So far I have been able to get attributes from TaskData. While this
works, it is slow and its clear that TaskData isn't intended for
frequent read access to TaskAttributes, so I'd like to find a more
efficient way, that fits with how Mylyn is designed.
- TaskData looks like it is intended to back task editing pages, not
every task show in a grid of 100s of tasks.
- TaskData is loaded from XML every time you ask for it
AbstractTask has an attribute Map, would it a sensible approach be to
put the few values I need to read often there - hoisting them up from
TaskData ?
- If so please advise on how to keep this view of attribute values in-sync
- What listeners and calbacks should I use to faithfully track the real
attribute values
- Idealy I'd like to see saved values (outgoing changes)
(In case you are interested, I'm using Nebula grid widget:

Thanks,
Mark
