function xautoload_ClassFinder_Prefix::findFile in X Autoload 7.3

Same name and namespace in other branches

1. 7.2 lib/ClassFinder/Prefix.php \xautoload_ClassFinder_Prefix::findFile()

Finds the path to the file where the class is defined.

Parameters

xautoload_InjectedAPI_findFile $api: API object with a suggestFile() method. We are supposed to call $api->suggestFile($file) with all suggestions we can find, until it returns TRUE. Once suggestFile() returns TRUE, we stop and return TRUE as well. The $file will be in the $api object, so we don't need to return it.

string $class: The name of the class, with all namespaces prepended. E.g. Some\Namespace\Some\Class

Return value

TRUE|NULL TRUE, if we found the file for the class. That is, if the $api->suggestFile($file) method returned TRUE one time. NULL, if we have no more suggestions.
