private function LibrariesLoad::librariesTraverseLibrary in X Autoload 7.5

Helper function to apply a callback to all parts of a library.

Because library declarations can include variants and versions, and those version declarations can in turn include variants, modifying e.g. the 'files' property everywhere it is declared can be quite cumbersome, in which case this helper function is useful.

Parameters

array $library: An array of library information, passed by reference.

callback $callback: A string containing the callback to apply to all parts of a library.
