Looking for suitable and robust data structure?

Question

I have an application where i have to give user an option to correlate the
response returned by a method call with other methods arguments.
I have provided a jtree struture where user can see methods and their
responses and can correlate them by selecting appropriate arguments
where these values could be used.
I used a data structure to store such relations like
A hashmap where every key is a unique number representing method number
and value ia a matrix.
In each matrix, the first element of every row would be the Response object and
all remaining elments in the row would be Argument objects. :)
Now maybe someone would ask, for every method there is always only one return type
then why such a matrix with Reponse object as first element of each row.
The reason is that i gave user an option to not only relate response as a whole Object to
different arguments of different methods but user can select a field of this response object if this
is a complex type or user can select any element if the response is a Collection object to relate
with arguments.
I am not sure whether this structure is more appropriate or i can use more robust
and memory efficient structure.
Please give me your useful suggestions.

I used a data structure to store such relations likeErr, what happened to the rest of your sentence? Or is the next part the rest of it?
A hashmap where every key is a unique number representing method number
and value ia a matrix.Where does this matrix come from? In my book, a matrix is a 2 dimensional structure. What do you mean by it?

Now maybe someone would ask, for every method there is always only one return type
then why such a matrix with Reponse object as first element of each row.You're still talking about methods? If so, don't all methods have just one return type?

Please give me your useful suggestions.Perhaps you could give a more detailed explanation and more importantly, provide some examples of what you mean.
