string $logical_path: Class name translated into a logical path, either with PSR-4 or with PEAR translation rules.

int|bool $lastpos: Position of the last directory separator in $logical_path. FALSE, if there is no directory separator in $logical_path.

Return value

bool|NULL TRUE, if the class was found.

File

lib/ClassFinder/GenericPrefixMap.php, line 197
