A parameter can be seen as a name/value pair in the DataTables configuration Javascript object.
Some extension may need to modify the DataTables parameters object, that's why there's a Mode attribute, which defines the way the configuration will affect this object.
For example, in order to use the {@link ScrollerPlugin}, you need to modify the sDom parameter, adding a S to the default value (which is lfrtip). That's why in the setup
method, you will find among others :
addParameter(new Configuration(DTConstants.DT_DOM, "S", Configuration.Mode.APPEND));
So the final value of the sDom parameter will be lfrtipS
