* Replaces the ProxyClassFinder in the ClassLoader with the real ClassLoader.
|
||
|
|
*
|
||
|
|
* xautoload has a number of cached class loaders, working with APC cache or
|
||
|
|
* other key-value stores.
|
||
|
|
*
|
||
|
|
* The cached class loaders use the decorator pattern, and decorate a
|
||
|
|
* ClassFinder object, that will only be consulted on a cache miss.
|
||
|
|
*
|
||
|
|
* xautoload will first give the ClassLoader a ProxyClassFinder that wraps the
|
||
|
|
* real class loader. On the first cache miss, this ProxyClassFinder will
|
||
|
|
* notify all subscribed CacheMissObserverInterface object.
|
||
|
|
*
|
||
|
|
* The job of this particular observer is to replace the ProxyClassFinder, once
|
||
|
|
* it has done its job. Instead, the ClassLoader will get a reference ot the
|
||
|
|
* real ClassLoader, saving the overhead of going through ProxyClassFinder each
|
||
|
|
* time.
