RE: [jdt-ui-dev] Faster Open-Type Dialog
|
Using JProbe, I found that the only *significant* cycles are spent in
Sorting the results (around 9% of the total time), and constructing
TableItems (90%). Caching won't bring down that last part.
Won't threading slow down the common case of when I am going to type 2 or
more characters? If you could abort the threading once the query has
become "specific" enough, that might help.
In WSAD, we have several Text entires that are timed. If typing stops for
about 1/2 of a second, the text is "committed". You could use this
approach to prevent the Thread from ever starting (in the 2+ character
case).

I fully agree that the Open Type dialog should be faster and we plan to
make it faster. I like the idea, but I'm reluctant to put it in without a
preference option. Since I'm sure we will get PRs as Scott has pointed out.
Here is what we are currently doing.
on first open
1) search for all types
2) show only the types starting with A initially in the dialog
3) cache the list of all types, the cache is flushed whenever a
type is added or deleted
4) as the user types create table items for all matches
on subsequent opens, reuse the cache if possible.
The most annoying step is 4) given that adding or deleting
types is rare and the cached type list should be up to date.
The annoyance is that the table population is done in the
UI thread. We are considering populating
the table table in batches in a background thread. The population
is pre-empted whenever the input changes.
Regarding single character class names. I looks like the crypto packages
contained in 1.4 were obfuscated.
To avoid the "i" import when developing
against 1.4 you can set the preference in organize imports to ignore
classes that start with lower case.

Actually, Sun has a class called "i".
And someone told me that there was a time when organize imports would find
a variable "i" in your code and import that class from Suns security
package.
Thanks Sun.

Nice idea... this would make an interesting option, though wording it right
would be tricky. I can see the first "Why can't I find class A?" complaint,
though...
A better complaint: "Why did you call the class A?"
