Interface IStreamStore

All Known Subinterfaces:

IStreamStoreWithBinary

All Known Implementing Classes:

StreamStoreFile, StreamStoreJDBC, StreamStoreWithBinaryWrapper

public interface IStreamStore

The stream store is a simple persistency mechanism for storing streams of data. The store is an abstraction of where the stream is actually managed - e.g. it may be managed within the file system or it may be managed within a relational database.

The stream store is used as "globally accessible file system". The most simple implementation is indeed a reflection of the stream store into the file system (and of course is nor suitable for cluster scenarios) - the higher level of implementation is a implemetation of the stream store using a database resource.

The class name for internally creating the IStreamStore instances is taken from the system.xml definition.
