Hi
* @Abel: is it possible to change the filtering partial
match after it
has been set for the first time. This is an important
question, because
when, for example, the patterns are reloaded, the
current match set will
be removed and it will be recreated.
Abel: Changing the filter match
(simply calling setParam) after setting it is not
supported. The EVM Rule must be removed and added with
the new filter.
* When a new filter is set in the UI, I also need to
update the contents
of the tree viewer. Can this be handled somehow with
this
ObservablePatternMatchList? Basically I would like to
see something like
setFilter, which would then update the contents
accordingly (and also
send the notifications about it).
Abel: Yes, it may possible to handle
this inside a setFilter method. You would need to (1)
disconnect the cache from the updater (2) remove the EVM
rule with the old filter (3) add the new rule with the
new filter (4) put matches into a new cache (5) create
diff between old and new cache and send it as list
update. Note that this is similar to the update
mechanism of computed lists, but we only have to do this
when setFilter is called, and it won't be called by
multiple threads at the same time for a given
observable.
Ok. Can you support me
with the implementation of such a functionality in the
ObservablePatternMatchList class? I have pushed a gerrit
code review with my initial contribution. This one does
not support the setting of a filter from the UI yet.
Cheers,
Tomi
