Webservices : missing methods

[saidmsl]

Hi

starting to play with webservices to create an independant interface 
so far , i was able to create the list view with columns labels, and related to names
but i had to check field by field 

i'm trying to duplicate the listview windows and notice methods missing

- how to get the list of all filters of a modules
- how to get the details of a filter : list of columns, conditions block
- how to get the query 

it's like rewriting the Customview.php file

what suggestions/ ideas ?
