function DrupalCoreRegistryPlugin::findFile in X Autoload 7.5
Find the file for a class that in PSR-0 or PEAR would be in $psr_0_root . '/' . $path_fragment . $path_suffix
E.g.:
- The class we look for is Some\Namespace\Some\Class
- The file is actually in "exotic/location.php". This is not following PSR-0 or PEAR standard, so we need a plugin.
-> The class finder will transform the class name to "Some/Namespace/Some/Class.php"
- The plugin was registered for the namespace "Some\Namespace". This is because all those exotic classes all begin with Some\Namespace\
-> The arguments will be: ($api = the API object, see below) $logical_base_path = "Some/Namespace/" $relative_path = "Some/Class.php" $api->getClass() gives the original class name, if we still need it. -> We are supposed to: if ($api->suggestFile('exotic/location.php')) { return TRUE; }
Parameters
InjectedApiInterface $api: An object with a suggestFile() method. We are supposed to suggest files until suggestFile() returns TRUE, or we have no more suggestions.
string $logical_base_path_empty: The key that this plugin was registered with. With trailing '/'.
string $relative_path_irrelevant: Second part of the canonical path, ending with '.php'.
Return value
bool|null TRUE, if the file was found. FALSE or NULL, otherwise.

// guessFile() instead of claimFile().
