The generic::Generic class represents generic "unknown" RDATA.
This class is used as a placeholder for all non well-known type of RDATA. By definition, the stored data is regarded as opaque binary without assuming any structure.

Constructor from a string.
This method constructs a generic::Generic object from a textual representation as defined in RFC3597.
If rdata_string isn't a valid textual representation of this type of RDATA, an exception of class InvalidRdataText or InvalidRdataLength will be thrown. If resource allocation to store the data fails, a corresponding standard exception will be thrown.
| rdata_string | A string of textual representation of generic RDATA. |

Constructor from wire-format data.
The buffer parameter normally stores a complete DNS message containing the generic RDATA to be constructed. The current read position of the buffer points to the head of the data.
This method reads rdata_len bytes from the buffer, and internally stores the data as an opaque byte sequence.
rdata_len must not exceed MAX_RDLENGTH; otherwise, an exception of class InvalidRdataLength will be thrown. If resource allocation to hold the data fails, a corresponding standard exception will be thrown; if the buffer doesn't contain rdata_len bytes of unread data, an exception of class isc::OutOfRange will be thrown.
| buff | A reference to an InputBuffer object storing the Rdata to parse. |
| rdata_len | The length in buffer of the Rdata. In bytes. |

Compare two instances of generic::Generic objects.
As defined in RFC4034, this method simply compares the wire-format representations of the two objects as left-justified unsigned octet sequences.
The object referenced by other must have been instantiated as a c generic::Generic class object; otherwise, an exception of class std::bad_cast will be thrown. Note that the comparison is RR type/class agnostic: this method doesn't check whether the two Rdata objects to compare are of the comparable RR type/class. For example, this object may come from an RRset of RRType x, and the other may come from a different RRset of RRType y (where x != y). This situation would be considered a bug, but this method cannot detect this type of error. The caller must ensure this condition.
| other | the right-hand operand to compare against. |
this would be sorted before other. this is identical to other in terms of sorting order. this would be sorted after other. Implements isc::dns::rdata::Rdata.
The assignment operator.
If resource allocation to copy the data fails, a corresponding standard exception will be thrown.
| source | A reference to a generic::Generic object to copy from. |

virtual |
Convert an generic::Generic object to a string.
This method converts a generic "unknown" RDATA object into a textual representation of such unknown data as defined in RFC3597.
If resource allocation to copy the data fails, a corresponding standard exception will be thrown.

Render the generic::Generic in the wire format into a MessageRenderer object.
This will require rdata_len bytes of remaining capacity in the buffer. If this is not the case and resource allocation for the necessary memory space fails, a corresponding standard exception will be thrown.
| renderer | DNS message rendering context that encapsulates the output buffer in which the Generic object is to be stored. |
