When it is necessary to hold information between decoding operations, a public constructor specifying the parameter com.neotys.extensions.codec.functions.contextual.Context must be declared.
The Context instance must be stored as a class field.
The lifespan of the Context depends on the operation:
Context lifespan is the duration of the recording.Context lifespan is the duration of the WebSocket channel (there are as many Contexts as WebSocket channels per Virtual User instance).
