Detailed Description

Interface for accessing external data using streams.

SLIOStream provides an interface to access files which may be stored in the native file system, on a remote server, in memory, etc. Streams should not be instantiated by users of the class, but by SLFileStorage::open, which selects the appropriate stream implementation for a given kind and mode.
