This is useful for both cleanly exiting from simulation and for unit testing
at a framework level.
This change required removing move constructor/assignment from IterativeRobot.
A templated hal::Handle class is used to wrap handles to make them move-only.
This eliminates a lot of boilerplate move constructor/assignment code
in the main WPILib classes. HAL_SPIPort and HAL_I2CPort are also wrapped.
The wrapper class does not implement destruction. This would require the
wrapper class to be handle-specific (rather than generic) and would result
in more code added than it removed, plus would add header dependencies on
more HAL headers. In addition, some HAL handle release functions are more
complex (e.g. have return values) and can't be easily mapped to a destructor.
Add unit-taking overloads to the following classes:
- IterativeRobotBase
- LinearFilter
- Notifier
- TimedRobot
- Timer (HasPeriodPassed only)
- frc2::PIDController
The corresponding non-units-taking functions have been deprecated.
The return value of TimedRobot::GetPeriod() was updated.
This is a breaking change, users should use to<double> to get the value in seconds.
Other return values, e.g. Timer::Get(), have NOT been updated due to much wider use.
This fixes two real bugs:
- TimedRobot had a m_period that was hiding the IterativeRobotBase m_period
and was not getting initialized.
- PDPSim was swapping two parameters to getCurrent()
The old headers were moved into folders because doing so avoids polluting
the system include directories.
Folder names were also normalized to lowercase.
