|
|
* is passed through manipulateStorageConfig() to update any parameters as
|
|
* necessary. After the storage implementation has been constructed, it is
|
|
* passed through wrapStorage(), potentially replacing the implementation with

* a wrapped storage that changes its behaviour.

|

* Certain configuration options need to be set before the implementation is
|
|
* constructed, while others are retrieved directly from the storage
|
|
* implementation and so need a wrapper to be modified.
