Detailed Description

An intermediate object for building a "controllable item", where an "item" can refer to multiple input parameters with different names.

The name supplied to the constructor is considered the "master" parameter. The parameter(s) added via the connect method are considered the slaves.

In general, an ControllableItem will have a one-to-one relationship with an input parameter value, but in some instances it is desirable to connect parameters with different names together. For example, within MOOSE when a material is defined in an input file multiple Material objects are generated automatically. If a parameter is controlled on one of these objects it is necessary to also have the values on the other controlled as well. This example is the driver behind the creation of this intermediate class.
