Multi-Protocol proxy support protocol adapters include: SNMP, TL1, RMI, CORBA, HTTP and HTML adapters.
In the process of actual development, we often come across such a thing, according to preliminary requirements for a base class, learned during the development process the detailed requirements or needs change. Interface is already defined in the development work, and had a large input encoding. If changes to the interface definition will cause a lot of repetitive modification work on the code, and thus may cause modification is not entirely as a result of semantic errors or logic errors. Semantic error can be found in the compile phase, and once a logical error occurs, the consequences will be very serious, even enough to cause the system to crash. Requires the use of the adapter pattern design method at this time.
