I am developing a code to make a comb filter within maxmsp using java. However I have stumbled upon a problem. Here is my code

public class IntelliTest extends MSPPerformer{

float []_circBuffer = sr; //defined in dsp setup method

declareInlets(new int[]{SIGNAL, DataTypes.FLOAT,DataTypes.FLOAT,DataTypes.FLOAT,DataTypes.INT,SIGNAL});

_delayTime = i; // need to convert to samples

post("Delay cannot be negative or exceed the buffer size");

post("Feedback cannot be negative or exceed 0.99"); //need to establish processing of other float inlets

As you can see I have missed out part of the code as I can't work out how to establish the other inlets within the code. For example I can access the delay time via float..but can't access any of the other inlets as I don't know how to number them. Do I use atoms?

    }

you need to tell the object to check which inlet has been used, this code is for 6 inlets (0,1,2,3,4,5) so for your float inlets you need to have the code like so ....

floatInlet = getInlet(); // this tells your inlet to check what inlet the signals are coming from

if (floatInlet == 1){ // this says if the info is coming in on inlet 1 then do such and such with the info

if (floatInlet == 2){ // this says if the info is coming in on inlet 2 then do such and such with the info

ps. you might wanna change Daves delay post comments. :-P

public void inlet(float f)
    {
        int floatInlet;
        floatInlet = getInlet();  // this tells your inlet to check what inlet the signals are coming from

        if (floatInlet == 1){     // this says if the info is coming in on inlet 1 then do such and such with the info
           do something
            }
        if (floatInlet == 2){     // this says if the info is coming in on inlet 2 then do such and such with the info
           do something else
           }
        etc....

As an aside, I've yet to be convinced that this technique (explicit callback to determine the inlet used) is thread-safe. It depends, I suppose, whether 

 contains a link to the thread which made the initial call to 

, but there's no mention of this in any of the documentation. So, you might want to think about using a 

 upstream to pack messages into one inlet with a prefix string to distinguish them.
