[JPP-Devel] Fwd: Weekly SoC Reports
Hi, In this week I work on my code. I finished same class like of my project core: ParameterSet, ProceduresIO and LibPatternsFactory. I made some test of this class and correct same errors. I hope to finish my core aplicattion after 1 month.

[JPP-Devel] Bunch of questions (mostly UI based)
After spending a bunch of time wading through code looking for answers and coming up short, I thought I'd ask the JUMP gurus on the list and see if anyone can shed some enlightenment... 1. In the MultiInputDialog that comes up when a plugin is executed: 1a. Is there a way to input a filename other than just a TextField? Specifically I want to have a TextField with an icon next to it that when clicked will bring up a file browser similar to the "open file" dialog. 1b. Is there a way to have a drop down set of layers that also include the option of not selecting a layer? IE "None - Layer1 - Layer2 - ... - LayerN" 2. How does JUMP deal with units? Is everything internally represented as meters and external data sources are required to do the conversion, or is there some sort of on the fly conversion available? 3. What is the most efficient 1-D spatial datastructure in the JTS index package: bintree, intervaltree, or SIRtree (the index won't be modified after initial loading, before any queries)? 4. In the layer manager panel on the left hand side: 4a. How do I change the font for a layer to bold? 4b. How do I add a visibility checkbox? 4c. How do I add an icon to the left of the visibility checkbox? 4d. Is there a way to have sub items for the layer. For instance if a TIN was created with different colored height bands, I'd like to display an icon of each color followed by the height range that color represents.

[JPP-Devel] DbfFile and String intern
Hi, I just replaced the String.intern() mechanism used in DbfFile to save memory heap space by the use of a temporary HashMap. Please, tell me if you notice any strange behaviour in the shapefile reader. For those of you interested by performance tuning, a short abstract of what we did to try to optimize DbfFile reader : Exemple : loading a 50 features with attribute A (50 different values) and attribute B (50 identical values) version 1 (original jump) : loads 50 strings for A + 50 strings for B in the jvm heap space ==> big waste of memory for case B version 2 (optimized by MM and Larry) : loads 50 strings in permgen memory for attribute A and 1 string in permgen memory for attribute B ==> need to tune max permgen memory when loading big shapefiles with attributes like A ==> permgen memory cannot be cleaned (no way to free the permgen space if the layer is deleted) ==> from my experience, the try/catch block added by Larry to switch from permgen space to heapspace in case or error did not prevent a permgen exception to rise and to stop the process version 3 (today) : loads 50 strings in the heapspace for A and 1 string in the heapspace for B ==> the loading guaranty unicity of field value for one layer only (string will be duplicated for each loaded layer) ==> all the strings are in the heapspace (and can be free if the layer is deleted) Michaël - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ ___ Jump-pilot-devel mailing list Jump-pilot-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/jump-pilot-devel
