Terminology

In the following text the place where an agent is created (with the agent keyword or the tilde operator) is called the agent creation. The feature to which the agent points is the callee and the place (or places) where the agent is called is denoted agent call.

            p: PROCEDURE [ANY, TUPLE]
        do
            p := agent target   -- agent creation
        end
 
    f2 (p: PROCEDURE [ANY, TUPLE])
        do
            p.call ([])         -- agent call
        end
 
    target                      -- callee

Wrapper generation

Lets look first at frozen workbench code. Class C is used throughout the following examples. 

class
    C
 
feature
    f (p1, p2: INTEGER; p3: STRING): STRING
        do
            ...
        end   
end

For everly agent creation a c-function is generated. This wrapper function does two things:

  • Reorder the closed and open arguments
  • Call the callee of the
