This is the changes made by Patrick Plenefisch converting the native code to use CMake and the CMake Maven Plugin, as opposed to the native Maven plugin. This is to allow for compatibility with newer versions of the GCC toolchain. All the cpp sources were moved from maven style directories to cpp style directories for CMake.

|
|
* 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.
