Re: [Nxtcommand-developers] static class vs. NetBeans vs. JavaBeans

[Brian B. <bba...@mt...>]

I think I have a solution to the singleton/multiple NXT/instantiated objects 
dilemma.

After reading about NetBeans, from what I can tell it's sort of an expanded 
version of JavaBeans that you can use visually in development environments 
like BlueJ, Netbeans IDE or Eclipse with the NetBeans plugin. The focus is 
making GUI apps that users can interact with visually. Also they can 
presumably be used as regular objects in plain text Java code, if we 
override the no-args constructor?

I think we should keep the current static/singleton setup that mirrors leJOS 
and keep it in the package icommand.platform.nxt, but we could add another 
package for the Netbeans implementation.

We should also aim for sharing common code between these two packages - for 
example, one place for code that calls Motor.forward(tacho) so that when we 
improve the accuracy of that call in one class it gets improved for all 
classes that use that call. It might be possible to just extend each Motor, 
Sensor, etc... class to make it into a Netbean? We need to figure out the 
proper architecture for this.
