question: TypeSimplifier ( Types typeUtils , String packageName , Set < TypeMirror > types , TypeMirror base ) { this . typeUtils = typeUtils ; Set < TypeMirror > typesPlusBase = new TypeMirrorSet ( types ) ; if ( base != null ) { typesPlusBase . add ( base ) ; } Set < TypeMirror > referenced = referencedClassTypes ( typeUtils , typesPlusBase ) ; Set < TypeMirror > defined = nonPrivateDeclaredTypes ( typeUtils , base ) ; this . imports = findImports ( typeUtils , packageName , referenced , defined ) ; }
target:  Makes a new simplifier for the given package and set of types.
