<title>Inheritance: object inheritance vs. layer inheritance</title>
|

|
|
<para>You might've read about layout inheritance (things not defined in a layout inherit from the core, for example) and read about the more familiar object inheritance (an undefined method <function>Poodle::bark()</function> inherits from <function>Dog::bark()</function>) and asked yourself…</para>

<para><emphasis>"How do object inheritance and layer inheritance interact? Which comes first?"</emphasis></para>
|
||
|
|

<para>If none of this makes sense, don't worry about it.</para>
