#include <FP.h>
Public Member Functions | |
| FP () | |
| Create the FP object - only one callback can be attached to the object, that is a member function or a global function, not both at the same time. | |
| template<class T > | |
| void | attach (T *item, retT(T::*method)(argT)) |
| Add a callback function to the object. | |
| void | attach (retT(*function)(argT)) |
| Add a callback function to the object. | |
| retT | operator() (argT arg) const |
| Invoke the function attached to the class. | |
| bool | attached () |
| Determine if an callback is currently hooked. | |
| void | detach () |
| Release a function from the callback hook. | |
Detailed Description
template<class retT, class argT>
class FP< retT, argT >
API for managing Function Pointers.
Example using the FP Class with global functions
#include "mbed.h" #include "FP.h" FP<void,bool>fp; DigitalOut myled(LED1); void handler(bool value) { myled = value; return; } int main() { fp.attach(&handler); while(1) { fp(1); wait(0.2); fp(0); wait(0.2); } }
Example using the FP Class with different class member functions
#include "mbed.h" #include "FP.h" FP<void,bool>fp; DigitalOut myled(LED4); class Wrapper { public: Wrapper(){} void handler(bool value) { myled = value; return; } }; int main() { Wrapper wrapped; fp.attach(&wrapped, &Wrapper::handler); while(1) { fp(1); wait(0.2); fp(0); wait(0.2); } }
Example using the FP Class with member FP and member function
#include "mbed.h" #include "FP.h" DigitalOut myled(LED2); class Wrapper { public: Wrapper() { fp.attach(this, &Wrapper::handler); } void handler(bool value) { myled = value; return; } FP<void,bool>fp; }; int main() { Wrapper wrapped; while(1) { wrapped.fp(1); wait(0.2); wrapped.fp(0); wait(0.2); } }
