Use of clone() in Java is tricky and questionable1,2. Effectively, clone() is a copy constructor and for that, the Dart List, Map and Set types each have a named constructor named .from() that perform a shallow copy; e.g. given these declarations Map<String, int> numMoons, moreMoons; numMoons = const <String,int>{ ‘Mars’ : 2, ‘Jupiter’ : 27 … Read more
Your problem is that your insertAfter: .insertAfter(“.tr_clone”) inserts after every .tr_clone: the matched set of elements will be inserted after the element(s) specified by this parameter. You probably just want to use after on the row you’re duplicating. And a little .find(‘:text’).val(”) will clear the cloned text inputs; something like this: var $tr = $(this).closest(‘.tr_clone’); … Read more
Shallow copy does not mean that they point to the same memory location. That would be just an assignment:List b = a;. Cloning creates a new instance, holding the same elements. This means you have 2 different lists, but their contents are the same. If you change the state of an object inside the first … Read more
You cannot provide options in the GIT_SSH environment variable; from the git man page: GIT_SSH If this environment variable is set then git fetch and git push will use this command instead of ssh when they need to connect to a remote system. The $GIT_SSH command will be given exactly two arguments: the username@host (or … Read more
If you want a copy of the HashMap you need to construct a new one with. myobjectListB = new HashMap<Integer,myObject>(myobjectListA); This will create a (shallow) copy of the map.
One way to do it is: $(document).ready(function() { $(“#container”).droppable({ accept: ‘.product’, drop: function(event, ui) { $(this).append($(“ui.draggable”).clone()); $(“#container .product”).addClass(“item”); $(“.item”).removeClass(“ui-draggable product”); $(“.item”).draggable({ containment: ‘parent’, grid: [150,150] }); } }); $(“.product”).draggable({ helper: ‘clone’ }); }); But I’m not sure if it is nice and clean coding.
ran into the same problem, simple solution: // touch all input values $(‘input:text’).each(function() { $(this).attr(‘value’, $(this).val()); }); var clones = $(‘input:text’).clone(); the trick is that this will change the actual ‘value’ attribute in the DOM tree, otherwise the data you enter ‘on-the-fly’ only exists in the DOM ‘state’
Clone is much faster than Storable::dclone, but the latter supports more data types. Clone::Fast and Clone::More are pretty much equivalent if memory serves me right, but less feature complete than even Clone, and Scalar::Util::Clone supports even less but IIRC is the fastest of them all for some structures. With respect to readability these should all … Read more
I resolved the same problem by this: git config http.postBuffer 524288000 It might be because of the large size of repository and default buffer size of git so by doing above(on git bash), git buffer size will get increase. Cheers!
As the manual says in Copying Databases you can pipe the dump directly into the mysql client: mysqldump db_name | mysql new_db_name If you’re using MyISAM you could copy the files, but I wouldn’t recommend it. It’s a bit dodgy. Integrated from various good other answers Both mysqldump and mysql commands accept options for setting … Read more
