@Override
        public @NonNull String processString(final @NonNull String input) {
            return input;
        }
Processes the {@code input} string and returns the processed result.
<p>
This should always return a non-{@code null} result. If the input string
isn't applicable to the processor implementation, the original string should
be returned.

@param input the input string
@return the processed string
