Forum OpenACS Q&A: proc_name in acs_sc_call

Here's how acs_sc_call works:

- Generate the name for the specified contract, implementation and operation. The proc name is a dotted expression of the form: AcsSc.${contract}.${operation}.${impl}

- If the proc exists, call it. Otherwise, do nothing.

Basically, the proc with name AcsSc.FtsContentProvider.DataSource.note (autogenerated proc by acs_sc_proc) would redirect a call like:

    acs_sc_call -contract FtsContentProvider -operation DataSource -impl note

to the concrete procedure that implements the ''DataSource'' operation of the contract ''FtsContentProvider'' in the implementation named ''note'', i.e to the proc ''notes__datasource'' defined in ''package/notes/tcl/notes-procs.tcl''.

I hope that helps.

That proc is nothing more but a redirect to the concrete/actual implementation (provided by ${impl}) of the abstract contract operation. Check out the following url that is the API documentation of the **autogenerated** proc for the redirection for the operation ''datasource'' of the
service contract ''FtsContentProvider'' based on the implementation named ''forums_message'':
