public abstract class InterpolationCommand<InputType>
extends CommandBase<InputType>

This is a "dummy" command which needs to be attached to a parent command that supports this type of command. This command will not be executed. Instead, the fetchCommands(Object) will be called to obtain the actual list of commands that will be executed. Hence, this command serves to interpolate the list of commands by adding more to the list. It must be used with caution since this can change the runtime execution command list
