com.fasterxml.jackson.core.JsonGenerator.writeObject()
Method for writing given Java object (POJO) as Json. Exactly how the object gets written depends on object in question (ad on codec, its configuration); for most beans it will result in Json object, but for others Json array, or String or numeric value (and for nulls, Json null literal. NOTE: generator must have its object codec set to non-null value; for generators created by a mapping factory this is the case, for others not.
