Meaning of DISTFIX

 
Computing Dictionary
 
 Definition: 

("distributed fixity"?) A description of an operator represented by multiple symbols before, between, and/or after the arguments.

The classical example is the c conditional operator, "?:" which is written

        E1 ? E2 : E3

If E1 is true it returns E2 otherwise it returns E3. Several functional programming languages, e.g. hope, haskell, have similar operators ("if E1 then E2 else E3").

objective c messages are effectively distfix operator applications:

        getRow:row andColumn:col ofCell:cell

is a message with three arguments, row, col, and cell.
