public interface AggStateBuilder<I,E,K,V>

• AggStateBuilderLiteral: Only used with @index as a leaf value. Emit a literal value.
• AggStateBuilderObject: Emits an object with start and end markers whenever a given expression evaluates to a new id.
• AggStateBuilderProperty: (possibly multi-valued, has targetNodeMapper) Produces a single JSON entry - emits a key. Does not emit object start/end markers. If the property is multi-valued, then the value will always be an array.
• AggStateBuilderLiteralProperty: Emit an entry, possibly array-valued. May omit output if the value is null.
• AggStateBuilderMap: Produces a set of JSON entries. Does not emit object start/end markers.
• AggStateBuilderFragmentHead: Condition whether to enter a state with a AggStateBuilderFragmentBody processor.
• AggStateBuilderFragmentBody: Emits a set of fields but does not emit start and end marker for objects - in contrast to AggStateBuilderObject.

The part below is wip: When turning a field into an Array then the parent becomes an AggStateBuilderArray, and the following changes apply to the children: We still need to match the transition, but we just don't need to emit the entry-key. So the only difference is whether to emit the key. In this case, a flag would be easier to use than a type hierarchy. AggStateBuilderProperty -> use its value. AggStateBuilderLiteralProperty -> use its value.
