[Help]difference between array.h and arrays.h

[cre8or]

I'm using c++ sdk to expose functions to maxscript(of course I am not so good at c++). I found that seemed no way to determine a value is ArrayParameter passed from mxs function. And when I looked into sdk documentation and those source code in .h files , I have found 2 " class Array" definition, 1st "class Array" is in arrays.h, derived from value and collection.  the other" class Array" is a template class under "maxsdk" namespace from array.h, derived from MaxHeapOperators.  Makes me confused with this two Array classes.which one should i use? how to deal with the value type determination? wait for help...

The array parameters I mentioned is the properties in array form like .maps property in standard materials, or .materiallist in multimaterial, etc. If there are other efficient way I can accept too.
