|

|
|
* @brief A base class for Adhoc Command plugins (DataForm, IO Data, ...).
|
||
|
|
*
|
||
|
|
* This is just a common base class for abstractions of protocols that can be embedded into Adhoc Commands.
|
||
|
|
* You should not need to use this class directly unless you're extending Adhoc Commands further.
|
||
|
|
*
|
||
|
|
* This class exists purely as an additional abstraction layer, to limit the type of objects that can be
|
||
|
|
* added to an Adhoc Command.
