constructor-arg, property relation in spring

I was reading following lines and I did not understand clearly.

Notice that <constructor-arg> can take a <ref> element just like <property> does.
In fact, you can use any of the same sub elements you used with <property> in the
same way when setting constructor arguments with <constructor-arg>.

Any ideas, resources,sample code,links, highly appreciated. thanks in advance.

its just saying you can pass beans to your constructor wiring in exactly the same way you pass then to your setter

i do not see any where setter in above description. you mean property. please advise
properties are set using setter methods

public void setBlah(MyBean blah) {
   this.blah = blah);
