Loads a previously saved document stream data from the specified cache.
public static Stream LoadStreamFromCache(
LoadFromCacheOptions options
)
public:
static Stream^ LoadStreamFromCache(
LoadFromCacheOptions^ options
)
def LoadStreamFromCache(self,options):
options
Options identifying the document to load.
The document stream if found in the cache; otherwise, null.
This method returns null if the data was in the cache but expired and was purged.
This method may also return null if the data was associated with a user token and the correct value was not passed in options . Refer to InvalidUserTokenException for more information.
Saving and loading from the cache is useful if the data is to be re-used between sessions in your application. The document identifier (_documentId_) is all that is needed to store in order to re-construct the document after saved to the cache and disposed. This ID can be stored in a database or passed to the client side as in the case of the LEADTOOLS Document Web Service.
