====== $p._callInit() – initialization helper ======

Helper method to call all ''init()'' methods of sub-objects of a passed code object.

<dl compact box outline>
<dt>Usage</dt>
<dd><strong>$p._callInit</strong>(<var>obj</var>, <var>pre</var>)</dd>
<dt>Member of:</dt>
<dd>[[framework:page:p-core:index|$p]] (core)</dd>
<dt>Parameters:</dt>
<dd><var>obj</var> – an object containing sub-objects which in turn contain ''_init()'' and/or ''init()'' functions (required) \\ <var>pre</var> – if <i>true</i>, the ''_init()'' methods will be called, otherwise ''init()'' (optional, default: <i>true</i>)</dd>
</dl>

Notes:

  * the called methods will be [[mdn>Web/JavaScript/Reference/Global_Objects/Function/bind|bound]] to their containing object. This means that ''[[mdn>Web/JavaScript/Reference/Operators/this|this]]'' is guaranteed to refer to the object they are in.

  * the called functions will have an (optional) parameter that refers to the //parent// object (i.e. to the <var>obj</var> that was passed to this function.

====== Example ======

This is an example of how the console ''init()'' implementation may look like:

<code JavaScript>
$p.console.init = function(parent) {
  this.setTarget(document.getElementById('console'));
}
</code>

As ''this'' refers to ''$p.console'', it can be used as a shortcut to the ''setTarget()'' method.

In this example, ''<var>parent</var>'' refers to ''$p'', though it could be omitted, as it is not used here.
