      • makeAccessible

        public static void makeAccessible​(java.lang.reflect.AccessibleObject object)
                           throws JsonIOException
        Internal implementation of making an AccessibleObject accessible.
        Parameters:
        object - the object that AccessibleObject.setAccessible(boolean) should be called on.
        Throws:
        JsonIOException - if making the object accessible fails

      • getAccessibleObjectDescription

        public static java.lang.String getAccessibleObjectDescription​(java.lang.reflect.AccessibleObject object,
                                                              boolean uppercaseFirstLetter)
        Returns a short string describing the AccessibleObject in a human-readable way. The result is normally shorter than Object.toString() because it omits modifiers (e.g. final) and uses simple names for constructor and method parameter types.
        Parameters:
        object - object to describe
        uppercaseFirstLetter - whether the first letter of the description should be uppercased

      • fieldToString

      • constructorToString

        public static java.lang.String constructorToString​(java.lang.reflect.Constructor<?> constructor)
        Creates a string representation for a constructor. E.g.: java.lang.String(char[], int, int)
