Function.Y()

Function.curry()

Method Function.call_callback()

Method call_callback

void call_callback(function f, mixed ... args)

Description

Call a callback function, but send throws from the callback function (ie, errors) to master()->handle_error. Also accepts if f is zero (0) without error.

Example

Functions.call_callback(the_callback,some,arguments);

equals
{
      mixed err=catch { if (the_callback) the_callback(some,arguments); };
      if (err) master()->handle_error(err);
   }

(Approximately, since call_callback also calls handle_error
 if 0 were thrown.)
