Deep Clone of array?

Ronald Fischer

8/9/2007 8:13:00 AM

Is there a standard way of doing a deep copy of an object (in
particular, of an array)?

http://www.ruby-doc.org/core/classes/Object.ht... mentions a
function 'dclone',
but this doesn't seem to exist:

undefined method `dclone'

copy_of_your_array = Marshal.load(Marshal.dump(your_array))

I've never seen that method. No idea.

Kind regards

It's annoying -- the ruby-doc core documentation includes all of the
standard library, so it's hard to tell what comes from where. (Perhaps
they can regenerate the documentation?)

Anyway, if you click on the function name, you'll see the source code:

# File lib/rexml/xpath_parser.rb, line 8
def dclone
clone
end

Marshal.load(Marshsl.dump(array))

Cut their losses by selling the dumpsters as scrap steel before that
market collapses.
