Method Detail

isInheritorOrSelf

public static boolean isInheritorOrSelf(PsiClass aClass,
                                        PsiClass baseClass,
                                        boolean checkDeep)

Parameters:

aClass - a class to check.

baseClass - supposed base class.

checkDeep - true to check deeper than aClass.super (see PsiClass.isInheritor(PsiClass, boolean)).

Returns:

true if aClass is the baseClass or baseClass inheritor

processSupers

public static boolean processSupers(PsiClass aClass,
                                    boolean includeSelf,
                                    Processor<? super PsiClass> superProcessor)

isInheritor

public static boolean isInheritor(PsiType type,
                                  java.lang.String baseClassName)

isInheritor
