Reconstructs a container of known type from JSON.
Reconstructs a container of known type from JSON. General users should call the Factory object's fromJson, which uses header data to identify the container type. (This is called by fromJson.)

Name of the concrete Factory as a string; used to label the container type in JSON.
Interface for a container factory, always named as imperative verbs, such as "Count" and "Bin".
Each factory has:
applymethod to create an active container than can aggregate data (and is therefore mutable). This active container is named by the gerund form of the verb, such as "Counting" and "Binning".edmethod to create a fixed container that cannot aggregate data (immutable), only merge with the+operator. This fixed container is named by the past tense form of the verb, such as "Counted" and "Binned".fromJsonFragmentmethod that can reconstruct a fixed (immutable) container from its JSON representation. This is used by theFactoryobject'sfromJsonentry point. (Click on the "t" in a circle in the upper-left to see theFactoryobject's documentation, rather than theFactorytrait.unapplymethods to unpack active and fixed containers in Scala pattern matching.
