Description copied from interface: Store

Selects a Repository configured for the given policy. The policy must be an instance of Configuration. The following attributes are used by the Store and thus are mandatory in the policy parameter:

 <repository destinationURL="[URL of this repository]"
             type="[repository type e.g. OBJECT, STREAM or MAIL]"
             model="[repository model e.g. PERSISTENT, CACHE]">
   [additional configuration]
 </repository>
 

The policy is used both to select the appropriate Repository and to configure it.

Specified by:

select in interface Store

Parameters:

policy - a Configuration object identifying the sought Repository

Returns:

requested Repository

Throws:

ServiceException - if no repository matches policy
