validateFragmentDataStructure function

bool validateFragmentDataStructure({ required DocumentNode document, required Map<String, dynamic>? data, String? fragmentName, Map<String, dynamic> variables = const {}, bool addTypename = false, bool handleException = false, })

Validates the structure of data against the fragment fragmentName in document.

Throws a PartialDataException if the data is invalid, unless handleException=true, in which case it returns false.

NOTE: while null data is a theoretically acceptable value for any fragment in isolation, we treat it as invalid here, maintaining consistency with denormalizeOperation.

Calls denormalizeFragment internally.

Implementation

bool validateFragmentDataStructure({
  required DocumentNode document,
  required Map<String, dynamic>? data,
  String? fragmentName,
  Map<String, dynamic> variables = const {},
  bool addTypename = false,
  bool handleException = false,
}) {
  return _validateSelectionSet(
    document: document,
    getSelectionSet: ({required document, required fragmentMap}) {
      return findFragmentInFragmentMap(
        fragmentMap: fragmentMap,
        fragmentName: fragmentName,
      ).selectionSet;
    },
    data: data,
    variables: variables,
    addTypename: addTypename,
    handleException: handleException,
  );
}
