AbstractProtocolDescriptor

protected AbstractProtocolDescriptor(int version,
                                     int architecture,
                                     int minimumType,
                                     int maximumType,
                                     int weight)

Initializes the basic ProtocolDescriptor fields.

Parameters:

version - Version of the protocol

architecture - Architecture of the protocol

minimumType - Minimum supported protocol type

maximumType - Maximum supported protocol type

weight - Preference weight
