function xautoload_Plugin_DrupalExtensionLibPrefixDeep::findFile in X Autoload 7.2

The way this plugin is registered, it will only ever be called if the class is not within a namespace. This means, all the DIRECTORY_SEPARATOR in the $path parameter were underscores before.

Parameters

xautoload_InjectedAPI_findFile $api: API object with suggestFile() method.

string $empty_string: The way we register this plugin, this parameter will always be empty string.

string $path: The class name converted into a path by usual PEAR rules. All underscores of the class name are replaced by DIRECTORY_SEPARATOR

Return value

boolean TRUE, if we found it.
