__whenMoreResolved/1 is a Miranda message.
__whenMoreResolved/1
- Signature: __whenMoreResolved(reactor :OneArgFunc) :void
The overall effect is to notify the reactor when the reference is resolved, or is closer to being resolved — in particular, when a resolution has changed its target to another vat. XXX poor terminology
If the recipient is a near ref, then the Miranda method should be:
to __whenMoreResolved(reactor) {
reactor <- run(recipient)
return null
}
? var r := null
> def ret := 1 <- __whenMoreResolved(fn x { r := x + 1 })
> interp.waitAtTop(ret)
> ret
# value: <Promise>
? r
# value: 2
? [ret]
# value: [null]
XXX Above tests do not check for reactor<-run rather than reactor.run
If the recipient is a local promise then it should buffer and forward the message normally.
If the recipient is a remote promise then XXX Specify the CapTP-related behavior.
