android - Is writting parcelable objects in a bundle that fast? -


i wanted estimate time needed write parcelable object in bundle. created own parcelable class (with 2 attributs : int , string) , wrote short application instanciates 500 000 objects of parcelable class, puts them arraylist, writes arraylist in bundle, , reads arraylist same bundle.

i surprised see writting , reading quite huge list instantaneaous. (0ms every time)

can such arraylist written "instantaneously", or doing wrong ?

i grateful can provide.

    ...      private static final int test_size = 500000;      ...      mlist = new arraylist<myparcelableclass>();     for(int i=0; i<test_size; i++){         mlist.add(new myparcelableclass(i));     }      ...       bundle testbundle = new bundle();      mstarttime = system.currenttimemillis();             testbundle.putparcelablearraylist("test", mlist);             logtime("parcelablearraylist writting");     //parcelablearraylist writting 0ms            arraylist<myparcelableclass> deserialization = new arraylist<myparcelableclass>();           mstarttime = system.currenttimemillis();             deserialization = testbundle.getparcelablearraylist("test");                    logtime("parcelablearraylist reading");     //parcelablearraylist reading 0ms       private void logtime(string msg){          long time = system.currenttimemillis() - mstarttime;          log(msg + " " + string.valueof(time) + " ms");     }         private void log(string msg){         log.i(tag, msg);     }

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
