Instance Method Details

#lookup_serializer(object, namespace: nil, serializer: nil) ⇒ Class<Transmutation::Serializer>

Lookup the serializer for the given object.

This calls Transmutation::Serialization::Lookup#serializer_for to find the serializer for the given object.

This also caches the result for future lookups.

Parameters:

  • object (Object) —

    The object to lookup the serializer for.

  • namespace (String, Symbol, Module) (defaults to: nil) —

    The namespace to lookup the serializer in.

  • serializer (String, Symbol, Class) (defaults to: nil) —

    The serializer to use.

Returns:

#serialize(object, namespace: nil, serializer: nil, depth: 0, max_depth: 1) ⇒ Transmutation::Serializer

Serialize a given object with the looked up serializer.

Parameters:

  • object (Object) —

  • namespace (String, Symbol, Module) (defaults to: nil) —

    The namespace to lookup the serializer in.

  • serializer (String, Symbol, Class) (defaults to: nil) —

  • max_depth (Integer) (defaults to: 1) —

    The maximum depth of nested associations to serialize.
