The Arbortext PE Request Manager calls the init method when it initializes. It takes an E3RequestContext object (described in Arbortext Publishing Engine Request Context Object) and a com.arbortext.e3cf.E3CacheManagerDescriptor as parameters.

The init method performs initialization for the cache manager object. If a cache manager can't initialize, it should throw an exception (using the class com.arbortext.e3.E3RequestException) with an error message explaining the circumstances causing the error.

The init method runs before the Sous-processus Arbortext PE start, so it can't retrieve data from an Sous-processus Arbortext PE to cache. To retrieve and cache data from an Sous-processus Arbortext PE, you need to develop and load an Sous-processus Arbortext PE Initializer (explained in Writing a Custom Initializer).
