setFrom method

@override void setFrom(CrystallisData other)

Copies compatible fields from any other instance of CrystallisData. Incompatible fields (missing or type-mismatched) are skipped. Null values are skipped.

Implementation

@override
void setFrom(CrystallisData other) {
  // skip this both this and other are of the same type
  final bool isSameType = this.runtimeType == other.runtimeType;

  for (final name in metadata.keys) {
    if (!isSameType) {
      final thisMeta = metadata[name]!;
      final otherMeta = other.metadata[name];

      /// TODO(kerberjg): dart-format-off is not working here...
      // skip when...
      if ( //
          otherMeta == null // missing
              ||
              otherMeta.type != thisMeta.type // type-mismatched fields
              ||
              !thisMeta.mutable // this field is immutable
          ) {
        continue;
      }
    }

    final value = other.get(name);

    // skip null values
    if (value != null) {
      set(name, value);
    }
  }
}
