Read the next token and raise an exception if it isn't EOL or EOF. Returns a string.

Return the number of cache hits associated with the specified key.

Read the next token and interpret it as a 16-bit unsigned integer. Raises dns.exception.SyntaxError if not a 16-bit unsigned integer.

How many hits has the cache had?

Return a new set which is the intersection of ``self`` and ``other``. Returns the same Set type as this set.
