MessageChannel provides the same functionality as MessageSend.
|
|
|
53 |
It has been provided for ST-80 compatibility.
|
|
|
54 |
|
|
|
55 |
Like with MessageSend, instances of MessageChannel can be used for
|
|
|
56 |
simulation programs.
|
|
|
57 |
They keep some receiver and selector and can be evaluated at any time later.
|
|
|
58 |
(think of them as a cheaper alternative to blocks).
|
|
|
59 |
|
|
|
60 |
In contrast to MessageSend, MessageChannels expect arguments to be passed
|
|
|
61 |
if all sends are going to the same receiver, use:
|
|
|
62 |
|
|
|
63 |
example:
|
|
|
64 |
|q|
|
|
|
65 |
|
|
|
66 |
q := Queue new:120.
|
|
|
67 |
1 to:100 do:[:i |
|
|
|
68 |
q nextPut:(MessageChannel receiver:i selector:#+).
|
|
|
69 |
].
|
|
|
70 |
[q notEmpty] whileTrue:[
|
|
|
71 |
|m|
|
|
|
72 |
|
|
|
73 |
m := q next.
|
|
|
74 |
(m value:1) printNL.
|
|
|
75 |
].
