This is a major restructuring of the WPILib repository to simply build procedures and remove the remnants of Maven from everything except the eclipse plugins. Gradle files have been largely simplified or rewritten, taking advantage of splitting up parts of the build into separate build files for ease of reading. The eclipse plugins are now in a separate project, as is ntcore. All dependencies are resolved via Maven dependencies, with the Jenkins-maintained WPILib repo. Project structures have also been simplified: we no longer have separate subprojects inside wpilibc and wpilibj. Where possible, these changes hav been done with git renames, to make sure we still have full history for all repositories. Other unrelated subprojects have also been broken out: OutlineViewer is now a separate project. Change-Id: Ib4e2a6e1a2f66427a14f16612b0e0d69ed661878

/**
|
|
* This class provides an easy way to link commands to inputs.
|
|
*
|
|
* It is very easy to link a polled input to a command. For instance, you could
|
|
* link the trigger button of a joystick to a "score" command or an encoder
|
|
* reaching
|
|
* a particular value.
|
|
*
|
|
* It is encouraged that teams write a subclass of Trigger if they want to have
|
|
* something unusual (for instance, if they want to react to the user holding
|
|
* a button while the robot is reading a certain sensor input). For this, they
|
|
* only have to write the {@link Trigger#Get()} method to get the full
|
|
* functionality
|
|
* of the Trigger class.
