The module native implements
the QueryAdapter
interface to use native query language part of the JM2MP
syntax.
By compliance with JM2MP, the
QueryAdapter
created by module:jm2mp/adapters/native.createNativeAdapter
is the reference for the expected behaviour that any other external
adapter must replicate.
Native query language offers two different but equivalent syntaxes:
- A text string path in compliance with native EBNF rules (e.g. "@.users[0].name").
- An array with literal accessors (e.g. ["users", 0, "name"]).
It is important to note that, although this adapter is
synchronous internally (it does not involve I/O or async libraries),
its evaluate function is marked as async just to comply with the
registry's uniform contract. The overhead of wrapping it in
Promise.resolve() is negligible and is offset by architectural
consistency (because other adapters are async, all of them would be
async).
