Deepcopy: Difference between revisions

=={{header|jq}}==

The distinction between "deep" and "shallow" copying is as irrelevant in a jq program as in elementary arithmetic. There is only one "equality" operator in jq and it is defined in terms of equality of values.

In PARI, this is accomplished with the command <code>gcopy</code> rather than <code>shallowcopy</code> or <code>leafcopy</code>. The function takes and returns a <code>GEN</code>. See section 10.6 of the [http://pari.math.u-bordeaux.fr/pub/pari/manuals/2.5.0/libpari.pdf User's Guide to the PARI Library].

use [http://search.cpan.org/perldoc?Storable Storable]; <code>Storable::dclone()</code> is exactly what you are looking for.

print Dumper($dst);

PHP provides the <code>clone</code> operator ([http://www.php.net/manual/en/language.oop5.cloning.php docs]) for shallow copying, and allows you to hook into a magic class method called <code>__clone()</code> in your classes to do some of the lifting to create deeper copies, but this method won't create a true deep copy if you don't write the code to manage it in each of the child classes.

deepcopy: (#0=(1 . #0#) #0#)

both: ((#0=(1 . #0#) #0#) (#1=(1 . #1#) #1#))
