ClassInfo
class ClassInfo (View source)
Provides introspection information about the class tree.
It's a cached wrapper around the built-in class functions. SilverStripe uses class introspection heavily and without the caching it creates an unfortunate performance hit.

'grandchildclass' => 'GrandChildClass'
)
