ItemSerializerValve
Valve for serializing the current set of items.
Item serializing means taking all items surviving the item include expression (if any) and convert them to json and store the result (encoded or not) in a property in the destination scope for later retrieval (deserialization).
Available destination scopes:
- item
- session
- attributes
By default serialized items are encoded in base 64 to avoid problems with embedded json.
De-serialization can be done using ItemDeserializerValve.
