Overview

Package jsonfieldnames contains a function to extract JSON field names from a value.

In addition to their fixed, hardcoded members, business objects for energy marshal additional values into Geschaeftsobjekt.ExtensionData. As Go's standard library JSON package has no option for a kitchen sink field accepting all remaining JSON fields, there are two passes of unmarshaling: Once into the struct, once into a generic map. To avoid duplicates in the struct and the map, fields that can be found in the struct are removed from the map. This package provides a mechanism to extract the names of these fields in a generic way.
