virtual |
Create message based on type name.
This will create a new message of the given type. The type must be given without the InterfaceName:: prefix but just the plain class name of the message.

virtual |
Convert arbitrary enum value to string.
Given the string representation of the enum type and the value this method returns the string representation of the specific value, or the string UNKNOWN if the value is not defined. An exception is thrown if the enum type is invalid.
