context, which await of doing one of blocked operations. We can look on one as on implementation of go select statement: we can add to context pairs of inputs and outputs, and then when some of inputs and outputs are non-blockde, than action is performed. I.e. next block of 'go' select:
for(;;) { select match case x <- a => f1(x) case x <- b => f2(x) case 1 -> c => f3 case _ => f4 }is mapped doslc = new SelectorContext() slc.addInputAction(a, x=>f1(x)) slc.addInputAction(b, x=>f2(x)) slc.addOutputAction(c, {f4; Some(1) } slc.addIddleAction(f4) slc.run()(and with help of macroses, can be write asselector match { case x <- a => f1(x) case x <- b => f2(x) case 1 -> c => f3 case _ => f4 }
