Name

call_other() - call a function in another object

Synopsis

mixed call_other( mixed ob, string func, ... );
mixed call_other( mixed ob, array args );
mixed call_other( array obs, string func, ... );
mixed call_other( array obs, array args );

Description

`ob' is either an object pointer, or a string filename (suitable for find_object()). `obs' is an array of object pointers and strings. Using an array as the first argument does a call_other for each element of the array, and returns an array of the results. If the array form is used for `args', then the first element is the function name, and the remainder are the arguments; e.g.:

call_other(ob, ({ "foo", 1, 3, 5 }))

and

call_other(ob, "foo", 1, 3, 5)

are equivalent. The function foo() is called in the object ob with the arguments (1, 3, 5). The return value of call_other() is the value returned from the foo() function. In the case of an array of objects, the return value of call_other() is an array of the return values.

There is a much more attractive way to do call_others; call_other(x, "y", z, ...) is the same as:

x->y(z, ...)

i.e.,

call_other(ob, "query_name");

could be written as:

ob->query_name();

Writing out the call_other call is mainly used when the function name is in a variable, i.e:

void do_test(string fname, int x) {
call_other(fname, "test_" + x);
}

An example of using an array as the first argument:

users()->quit();
