How do you get interrupt when digital input is set

[ericalbers]

Is there code showing how to get a interrupt when say a limit switch is hit?

I see the
public abstract class InterruptHandlerFunction<T>

is there example code of how to implement this for the requestInterrupts off DigitalInputs?
I'm having trouble with how to define the polymorphism of the function properly.

Thanks

This is how I used interrupt handlers in a gyro driver. The really wierd part about it is that the interruptFired() method is package private, so any class that uses it needs to be in the edu.wpi.first.wpilibj package. I think this was an oversight on the part of the authors of WPILib.

DigitalInput interrupt = new DigitalInput(0);

// Register an interrupt handler
interrupt.requestInterrupts(new InterruptHandlerFunction<Object>() {

     @Override
     public void interruptFired(int interruptAssertedMask, Object param) {
          // Do stuff
     }
});
// Listen for a falling edge
interrupt.setUpSourceEdge(false, true);
// Enable digital interrupt pin
interrupt.enableInterrupts();

Thanks, actually the private part is what was reallly killing me, I just could not get the thing to be happy I had the same code...

testinput =new DigitalInput(0);


testinput.requestInterrupts(new InterruptHandlerFunction<Object>()
{

@Override
public void interruptFired(int interruptAssertedMask, Object param)
{

}
});

I just couldn't get it to like the interruptFired no matter how I set it up...the base class having an error explains it though
Thanks

How much code do you plan to put into the interrupt routine?
