function uuid_file_entity_features_rebuild_files in UUID Features Integration 7

Runs the file import multiple times to resolve dependencies.

We might need several runs of ths function to resolve the dependencies created by reference fields. Those can only be resolved if the target file already exists.

Parameters

array $files: The files to process.

string $module: The module to rebuild for.

int $max_nesting: Maximal nesting level.

int $nesting_level: Current nesting level.

Return value

bool TRUE if all files could be restored.
