This function attempts to dynamically load a class which implements the specified rdata class and type. If there is no class-and-type-specific implementation, the GenericRdata class is used. Once a class is chosen, its from_text() class method is called with the parameters to this function. If *tok* is a ``str``, then a tokenizer is created and the string is used as its input. *rdclass*, an ``int``, the rdataclass. *rdtype*, an ``int``, the rdatatype. *tok*, a ``dns.tokenizer.Tokenizer`` or a ``str``. *origin*, a ``dns.name.Name`` (or ``None``), the origin to use for relative names. *relativize*, a ``bool``. If true, name will be relativized. *relativize_to*, a ``dns.name.Name`` (or ``None``), the origin to use when relativizing names. If not set, the *origin* value will be used. *idna_codec*, a ``dns.name.IDNACodec``, specifies the IDNA encoder/decoder to use if a tokenizer needs to be created. If ``None``, the default IDNA 2003 encoder/decoder is used. If a tokenizer is not created, then the codec associated with the tokenizer is the one that is used.
