There was an extension done for Java in 2005 that made async Java quite
nice;
http://en.wikipedia.org/wiki/Join_Java
The Join Java extension introduces three new language constructs:
- Join methods
- Asynchronous methods
- Order class modifiers for determining the order that patterns are
matched
... Join calculus ... has explicit synchronization based on a localized
conjunction of events defined as reduction rules. Join semantics try to
provide explicit expressions of synchronization without breaching the
object-oriented idea of modularization, including dynamic creation and
destruction of processes and channels.
class JoinExample {
int fragment1() & fragment2(int x) {
//will return value of x
//to caller of fragment1
return x;
}
}
PS. this came out of the same lab that Odersky did Pizza (
http://pizzacompiler.sourceforge.net), that became Generic Java, that became
generics in Java (but don't hold that against it)
