* A cache session represents a client's access into the cache. The cache
|
|
* session is not "owned" by the cache service. Hence, it is possible to
|
|
* create duplicate cache sessions. Entries created by a cache session

* equivalent.

|
|
* @param storagePolicy - Limits the storage policy for all entries
|
|
* accessed via the returned session. As a result, devices excluded
|
|
* by the storage policy will not be searched when opening entries
|
|
* from the returned session.
|
|
* @param streamBased - Indicates whether or not the data being cached
|
|
* can be represented as a stream. The storagePolicy must be
|
|
* consistent with the value of this field. For example, a non-stream-
|
|
* based cache entry can only have a storage policy of STORE_IN_MEMORY.

* @return new cache session.
