<h1>Scheduler Class</h1>
|
|
<p>The Scheduler class maintains a list of fibers, to be started one after the other, when a signal to do so is received. The signal (a private method call) is typically transmitted by <em>long running</em> methods in the File or Timer classes which suspend the current fiber so that Wren can carry out other tasks in the meantime.</p>
|
|
<h2>Static Method <a href="#static-method" name="static-method" class="header-anchor">#</a></h2>
|
|
<h3>Scheduler.<strong>add</strong>(callable) <a href="#scheduler.add(callable)" name="scheduler.add(callable)" class="header-anchor">#</a></h3>
|
|
<p>Adds a new fiber to the scheduler’s fibers list. This fiber calls <code>callable</code> and then transfers to the next fiber in the list, if there is one.</p>
|
|
<p><code>callable</code> is a function or other object which has a call() method.</p>

var a = 3

|
|
|
Scheduler.add {
|
|
a = a + 1

|
}
|
|
|
|
System.print(a) // still 3
|
|
Timer.sleep(3000) // wait 3 seconds
|
|
System.print(a) // now 3 * 3 + 1 = 10
