// CLASS DESCRIPTION (MComputation)
|
|
//
|
|
// An MComputation allows long computations to check for user interrupts. It is
|
|
// very simple to use. Create a new MComputation object and call the
|
|
// beginComputation method at the beginning of the computation and call
|
|
// the endComputation method when you finish. Then, during the computation,
|
|
// use the isInterruptRequested method to check if the user has requested
|
|
// that the computation terminate.
|
|
//
|
|
// Example:
|
|
//
|
|
// MComputation computation;
|
|
// computation.beginComputation();
|
|
// for (int i= 1; i<1000; i++) {
|
|
// Computation(); // Some expensive operation
|
|
// if (computation.isInterruptRequested()) break ;
|
|
// }
|
|
// computation.endComputation();
|
|
//
