isAccessibleFromPackage

public static boolean isAccessibleFromPackage(IMember member,
                                              String packageName)

Check whether member (field, method, constructor) is accessible from package, i.e., an unrelated class in package packageName. If not, attempting to access the member from the package should throw IllegalAccessException

public static boolean isAccessibleFromPackage(IClass memberClass,
                                              String packageName)

isAccessibleFromClass

public static boolean isAccessibleFromClass(IMember accessedMember,
                                            IClass accessedClass,
                                            IClass accessingClass)

Check whether accessedMember (field, method, constructor) of expression with type accessedClass is accessible from class accessingClass. Note that accessedMember may be inherited from a superclass of accessedClass

isAccessibleFromClass

public static boolean isAccessibleFromClass(IClass accessedMemberClass,
                                            IClass accessedClass,
                                            IClass accessingClass)

Check whether accessedMemberClass, an inner class or interface of accessedClass, is accesible from accessingClass. Note that accessedMemberClass may be inherited from a superclass of accessedClass.
