Interface BinaryStateCodec

All Known Implementing Classes:

CompositeCodec, CompressionCodec, ConfidentialityCodec, IntegrityCodec, PooledCodec

public interface BinaryStateCodec

Instances of a binary state codec can be added to any AbstractFlowStateStorage to transform the binary representation of the serialized state. Tipically, you will add codecs when using ClientSideFlowStateStorage to compress, encrypt, and/or digitally sign the state before passing it to the client.
