validateIntegrity method

@override VerificationContext validateIntegrity(Insertable<Tile> instance, { bool isInserting = false, })

Validates that the given entity can be inserted into this table, meaning that it respects all constraints (nullability, text length, etc.).

Implementation

@override
VerificationContext validateIntegrity(Insertable<Tile> instance,
    {bool isInserting = false}) {
  final context = VerificationContext();
  final data = instance.toColumns(true);
  if (data.containsKey('id')) {
    context.handle(_idMeta, id.isAcceptableOrUnknown(data['id']!, _idMeta));
  }
  if (data.containsKey('source')) {
    context.handle(_sourceMeta,
        source.isAcceptableOrUnknown(data['source']!, _sourceMeta));
  } else if (isInserting) {
    context.missing(_sourceMeta);
  }
  if (data.containsKey('z')) {
    context.handle(_zMeta, z.isAcceptableOrUnknown(data['z']!, _zMeta));
  } else if (isInserting) {
    context.missing(_zMeta);
  }
  if (data.containsKey('x')) {
    context.handle(_xMeta, x.isAcceptableOrUnknown(data['x']!, _xMeta));
  } else if (isInserting) {
    context.missing(_xMeta);
  }
  if (data.containsKey('y')) {
    context.handle(_yMeta, y.isAcceptableOrUnknown(data['y']!, _yMeta));
  } else if (isInserting) {
    context.missing(_yMeta);
  }
  if (data.containsKey('bytes')) {
    context.handle(
        _bytesMeta, bytes.isAcceptableOrUnknown(data['bytes']!, _bytesMeta));
  } else if (isInserting) {
    context.missing(_bytesMeta);
  }
  if (data.containsKey('etag')) {
    context.handle(
        _etagMeta, etag.isAcceptableOrUnknown(data['etag']!, _etagMeta));
  }
  if (data.containsKey('updated_at')) {
    context.handle(_updatedAtMeta,
        updatedAt.isAcceptableOrUnknown(data['updated_at']!, _updatedAtMeta));
  }

        lastAccessed.isAcceptableOrUnknown(
            data['last_accessed']!, _lastAccessedMeta));
