[NAME] ALL.dao.concurrent.asyncall [TITLE] Asynchronous Function Call [DESCRIPTION] Asynchronous Function Call (AFC) allows a function call to be executed as a tasklet, and return immediately a future value that can be use to block on the tasklet and wait for its completion. Any standard function call followed by !! will start an AFC. 1 routine MyFunction( n = 10 ) 2 { 3 for( i = 1 : n ) io.writeln( i ) 4 } 5 f = MyFunction( 20 ) !! 6 io.writeln( f.value() ) When multiple methods of a class instance are called in asynchronous mode, their execution will be mutually exclusive, namely, at any given time only call (tasklet) can be active. So in this way, the class instance acts just like a monitor.
