MBeanOperationInfo impact

[~matt();]

There's an MBeanOperationInfo c'tor which looks like

public MBeanOperationInfo(String name,
 String description,
 MBeanParameterInfo[] signature,
 String type,
 int impact)

The last parameter, impact, is one of (ACTION, INFO, ACTION_INFO, UNKNOWN). Where is this information used? I'm curious because I'm thinking about skipping this information in my abstraction as I don't see any use for it.

Thanks,

It's there for your own use. Those indicate if your operation provides information, does something interesting, or not specified. A good analogy would be GET/POST in HTTP.

I think it matters when you do dynamic mbeans. The behaviour that you get on a Console is dependent onwhat value you specify for the impact. If its ACTION, you would get a UI that lets you change the values for the attributes. Having it as INFO will only allow Read only views. Having ACTION_VIEW is a read/write property.
