Java Development

[rcmaniac25]

Ok, when I first started developing for BlackBerry, I wanted a bunch of features from .Net within BlackBerry (as I am a .Net developer). I created a personal library that I called "Rebuild". A few months before Dev Con 2011, I decided to open source most of it and call it BlackBerry eXtensions (BBX). At Dev Con 2011 BBX was announced and I had an idea for something else called BBX so I decided to make it a placeholder.

Regardless, I finally released the code. Let me know what you think, or should add.

do you have some more information what you have in the library?

*facepalm* Good point, forgot them.

• CustomButtonField: A simple button field that can have a picture, text, or both visible on the button.
• GestureField: A base field that allows for handling of different gestures and pinch to zoom.
• Image encoders: BlackBerry has image decoders (EncodedImage) but only a couple encoders. Supported image encoders-JPEG, PNG, TIFF (customizable with tag support), WBMP
• Version: Standard "version" data type.
• General utilities:
• assert
• permissions
• String utilities:
• isNullOrEmpty(orWhitespace)
• split
• format (based off java.text.MessageFormat, though number specific number formating isn't supported [#.##])
• MathUtilties: A math utilties class that is supported from OS 4.5 and up (as the built in MathUtilties varies based on OS level)
• GraphicsUtilites:
• Convert to and from EncodedImage/Bitmap/J2ME Image
• Save EncodedImage/Bitmap/J2ME Image to file
• Load EncodedImage/Bitmap/J2ME Image from file
• IO utilities:
• Directory/File exists
• EnsureCreation (makes sure that a file or directory that will be in use is created)
• Directory/File delete
• Directory/File move
• General path functions
• "reference" types: Allows for parameters to be passed into a function, and for the function to be able to modify the values and the changes will be retrievable from outside of the function. If you ever worked with C#, this is similar to the "ref" parameter keyword or passing a pointer to a variable in C/C++.

It's not complete, but also isn't really supposed to be. It's just a general collection of functions/utilites that I have found useful and implemented. If you have any ideas for stuff I should add, let me know and I'll see what I can do.

Is that better?

I have only taken a quick look at some of the classes, but it seems that the classes are well written and even contain meaningful comments.
I'll take a closer look later, to see if I can use any of these for a current project, and will share the link with my colleagues.

We have a similar library, but as it is property of the company i am working for I cannot share any of it.

Kudos to you to share your hard work, i would suggest that you go ahead and post the link whenever a question is raised that could be solved with one of your tools (as you have the best overview).

Thank you (on the code comment).

I plan to.

I realized I should have done this a while ago and just never got around to it.

Ok, I realized I had a bunch of other helper functions/classes from a couple of my other libraries, so I decided to move them over too.

Version 1.2: http://bbx.codeplex.com/releases/view/86030
