question: public static Map < String , MappedClass > mappingsFromEnigma ( File file , Map < String , ClassNode > nodes ) { Map < String , MappedClass > base = mappingsFromNodes ( nodes ) ; MappingLoader loader = new EnigmaLoader ( nodes ) ; try { Map < String , MappedClass > newMappings = loader . read ( new FileReader ( file ) ) ; for ( MappedClass mappedClass : newMappings . values ( ) ) { newMappings = linkMappings ( mappedClass , newMappings ) ; } base = fixFromMappingsText ( base , newMappings ) ; } catch ( FileNotFoundException e ) { e . printStackTrace ( ) ; } return base ; }
target:  Returns a map of class names to MappedClasses given an Engima mapping file.
