The BDiscreteParameter class represents a parameter that is set to one of a discrete set of values, and is usually used for non-linear values such as color spaces, multiplexers, and mutes or enables.

Each discrete value has a name that's displayed to the user by applications that draw a user interface for the node.

The default system theme renders these as BCheckBox controls, BRadioButton groups, or BMenuField controls, depending on the parameter kind. Other themes might implement these differently.
