Re: How to apply multiple values to a function

[Moe Aboulkheir]

Renata,

It depends on what you want to with the results of treat-request.  If you
don't care about them, which seems like the case:

(doseq  [[x y z] [x1 y1 z1] [x2
y2 z2] [x3 y3 z3]]
  (treat-request x y z))

Is one way to accomplish it.  If you want a collection of the results,
replace doseq with for  (maybe
take a look at doall , also).

In terms of the general approach - if the goal is to end up with a sequence
containing only the specified keys from each map (i.e. the 'collection'
argument is the same for all invocations), then you can accomplish this
without an atom:

(for [[m ks] [[m1 ks1] [m2 ks2] ...]]
  (select-keys m ks))

Does just that.

Take care,
Moe

How to apply multiple values to a function

[Renata Soares]

Good night,

I have this function: 

(defn treat-requests [input key-request collection]
(let [selecteds (select-keys input key-request)]
(swap! collection conj selecteds)))

and I want to execute that 3 times with 3 differents arguments

How can I do to apply a list of differents arguments to a function?

Instead of calling 3 times like:

(treat-request x1 y1 z1)
(treat-request x2 y2 z2)
(treat-request x3 y3 z3)

I want to call one time. For example... (apply treat-request [x1 y1 z1] [x2 
y2 z2] [x3 y3 z3])
