Json

sealed abstract
class Json

This AST of JSON is made available so that arbitrary JSON may be included as part of a business object, it is not used as an intermediate representation, unlike most other JSON libraries. It is not advised to .map or .emap from these decoders, since a higher performance decoder is often available.

Beware of the potential for DOS attacks, since an attacker can provide much more data than is perhaps needed.

Also beware of converting Num (a BigDecimal) into any other kind of number, since many of the stdlib functions are non-total or are known DOS vectors (e.g. calling .toBigInteger on a "1e214748364" will consume an excessive amount of heap memory). JsonValue / Json / JValue

  • merging objects results in a new objects with all pairs of both sides, with the right hand side being used on key conflicts

  • merging arrays results in all of the individual elements being merged

  • scalar values will be replaced by the right hand side
