• This example shows how to create a CircularDelayLine, load it with values, and retrieve those values from the buffer:

  // isip include files
  //
  #include<CircularDelayLine.h>
  #include<Float.h>
  
  // main program starts here
  //
  int main() {
         
     // declare a CircularDelayLine object of length 3
     //
     CircularDelayLine<Float> cdl(3);
         
     // place 3 items on the buffer
     //
     for (long i = 0; i < 3; i++) {
       Float tmp((float)i);
       cdl.assignAndAdvance(tmp);
     }
         
     // retrieve 3 items from the buffer in reverse order
     //
     for (long i = 0; i < 3; i++) {
       Float tmp = cdl(-i);
     }
         
     // you can also retrieve items in the forward direction
     //
     for (long i = 0; i < 3; i++) {
       Float tmp = cdl(i);
     }
  
     // exit gracefully
     //
     Integral::exit();
