[jboss-as7-dev] CLI new (generic type) commands

[Alexey Loubyansky]

So, I've pushed the prototype for the new approach. 
http://community.jboss.org/wiki/GenericTypeCLICommands


Advantages

- any changes in the management model (added/removed operations, 
properties, etc) become immediately available in CLI commands without 
code changes in the CLI;

- command help content is generated from the description of type, 
operations and properties in the management model (so, no text 
duplication, localization, etc);

- commands can be added and removed at runtime and customized by the user;

-the total number of cli commands will decrease and they, in a way, will 
be better categorized.


Disadvantages

Tab-completion suffers from insufficient info in the management model 
about the types, values and relationships/dependencies between the node 
and operation properties.

- enumeration values, if the type is boolean, I can do it, but if it's 
something else (e.g. tx isolation) the allowed values would have to be 
specified in the management model for the type in fixed format;

- exclusive properties, e.g. driver-class/driver-name for datasources. 
If I code the data-source command myself I can automatically exclude one 
if the other one has been specified;

- referencing properties, e.g. driver-name accepts values that are 
registered jdbc driver names, for that to tab-complete, this reference 
would have to be described in the model.

There are probably other things that I forgot to mention. I'll follow up 
if I remember something.

As always, feedback, ideas, suggestions are welcome.

Thanks,
Alexey

PS: it's not yet in the master as I send it, I did send the pull request 
though, so, it's gonna be soon.
