rdata::generic::MINFO class represents the MINFO RDATA as defined in RFC1035.
This class implements the basic interfaces inherited from the abstract rdata::Rdata class, and provides trivial accessors specific to the MINFO RDATA.

Compare two instances of Rdata.
This method compares this and the other Rdata objects in terms of the DNSSEC sorting order as defined in RFC4034, and returns the result as an integer.
This is a pure virtual method without the definition; the actual comparison logic is specific to each derived concrete class and should be explicitly defined in the derived class.
Specific implementations of this method must confirm that this and the other are objects of the same concrete derived class of Rdata. This is normally done by dynamic_cast in the implementation. It also means if the assumption isn't met an exception of class std::bad_cast will be thrown.
Here is an implementation choice: instead of relying on dynamic_cast, we could first convert the data into wire-format and compare the pair as opaque data. This would be more polymorphic, but might involve significant overhead, especially for a large size of RDATA.
| 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.

NS::getNSName()), this method constructs a new Name object and returns it, instead of returning a reference to a Name object internally maintained in the class (which is a private member). This is based on the observation that this method will be rarely used and even when it's used it will not be in a performance context (for example, a recursive resolver won't need this field in its resolution process). By returning a new object we have flexibility of changing the internal representation without the risk of changing the interface or method property. The same note applies to the getEmailbox() method.

Define the assignment operator.
| std::bad_alloc | Memory allocation fails in copying internal member variables (this should be very rare). |

This method returns a std::string object representing the Rdata.
