Othmen Tiliouine updated COLLECTIONS-448:
-----------------------------------------
Description:
Hello,
This is a patch to add two methods to Bag interface and classes
public E pick();
public E pickAndRemit();
as discussed in this mail.
-----------------------------------------------------------------
http://mail-archives.apache.org/mod_mbox/commons-dev/201303.mbox/%3CCAChO4O-YRE%3Db1%3D4hEK%2BuhvpV6-OD3F3apyRn3mwjvGzUEXe%2BaQ%40mail.gmail.com%3E
I just saw the Bag interface and its implementations, I'm surprised that Bag
<T> (and none of these implementations) expose the method
public T pick() and public T pickAndRemit() (pick a random element)
The Bag object we see in nature, it is mainly used to this, that's why it is
widely used in the probability that when I met 2 white balls and one black,
when I draw a ball randomly I have 2 times more likely to have a white ball
I think that if this caracteristic exists it would be very valuable.
----------------------------------------------------------------------
these methods pick a random element from the bag, The probability of picking a
copy of a given element is proportional to the number of copies of this element
in the bag.
the diference between pick() and pickAndRemit() is that with pick() the picked
element is removed from the bag.
this is my first contribution on open source project
if you accept to add this feature to bags and validate my patch i will add one
other patch to add this methods
public Iterator<E> pick(int n); //pick random n element (with remove)
public Iterator<E> pickAndRemit(int n) ; //pick random n element (without
remove)
-Question : should i regenerate the serialVersionUID of classes that i have
changed ?
