You also might consider replacing the TUPLE with an actual class, perhaps one the inherits COMPARABLE, so that you can enable sorting (a common requirement in such cases) I find that, while I might start with a TUPLE for convenience, a "first class class" often enters the scene not long into the

I now understand your question better. "... my question is how to use the other way (like array) to replace the hash table?" First—I would use ARRAYED_LIST just because generally, I find it easier to use than ARRAY. However, that is not to say that one ought never or even rarely use ARRAY.

The first thing to note is that the following code will only catch one duplicate date (e.g. 3 or more readings on the same day). hash.put (data_arr, date) if not hash.inserted then date.append ("_double_date_stamp") hash.put (data_arr, date) end You might want to consider adding a serializing

This now makes more sense! Thank you for the description and small sample data. On Monday, July 6, 2020 at 10:06:01 AM UTC-4 youha...@gmail.com wrote: > > > On Thursday, 2 July 2020 09:38:09 UTC-4, haiyong you wrote: > >> Hi everyone, >> >> I'm new beginner of Eiffel language, now I'm looking for

We are performing a review of Eiffel library mechanisms to make sure that simple everyday tasks are easy. From your point of view, are there libraries that you commonly need and do not find?Please share in the following format: * library/tool name * Description of the library/tool --Javier

Hi guys, Thanks for your suggestions, here is the program description: I have to analyse data files that have the following format: Each row corresponds to 1 day and the field logic is: $1 is the date, followed by 24 value/flag pairs, representing measurements at 01:00, 02:00 ... 24:00 of the

Actually to add something more, you could take a loook at the HASH_TABLE_ITERATION_CURSOR class to see what you can do with the cursor of the iteration On Thursday, July 2, 2020 at 12:01:00 PM UTC-4, Gachoud Philippe wrote: > > I'm feeling as Larry actually, but maybe your question is about

I'm feeling as Larry actually, but maybe your question is about iterating the has_table to get the values and keys, to get the arrays you put into... does that help? across hash as l_hash_table_cursor do l_item_key_in_your_case_string := l_hash_table_cursor.key l_item_value_in_your_cas

For me, it would be useful to have some sample data and a written description of the goal of this class. With that additional context, I can then understand your question. Right now, I am lost. Sorry. On Thursday, July 2, 2020 at 9:38:09 AM UTC-4 youha...@gmail.com wrote: > Hi everyone, > > I'm

Hi everyone, I'm new beginner of Eiffel language, now I'm looking for some help of an Eiffel program. In this example, Eiffel used hash table to store the data reading from a text file, my question is how to use the other way(like array) to replace the hash table? Thanks! class APPLICATION

That fixes it. BTW—the preferences dialog works just fine with no catcall error. On Friday, June 26, 2020 at 8:52:28 AM UTC-4 kwa...@mail.ru wrote: > There seems to be a bug in class PREFERENCES_WINDOW, feature > `on_grid_item_double_pressed`: the last formal argument should be > detachable.

There seems to be a bug in class PREFERENCES_WINDOW, feature `on_grid_item_double_pressed`: the last formal argument should be detachable. You can try editing the source code and rebuilding the project to see if this change fixes the issue. BTW, the class is marked as obsolete, there are two

If so I’d like to know. I tried over a decade ago to make this happen – but Apple moved too fast, probably because the technology is moving that fast. I started out with CodeWarrior and OS 9. I had a really decent library interface for OS 9, but then Steve Jobs came back and OS X completely

Hi Gary! I have been resisting using a beta. Also, I forgot to mention that clicking on the "check for updates" in the Help > About dialog informs me that I am using the latest version. So, I suppose I will limp along until a new release of ES is out. Perhaps we'll have a 20.06 or so, soon! :-)

I suggest the latest beta (which is what 19.12 actually is...a beta). Sent from my iPhone On Jun 23, 2020, at 9:21 AM, Larry Rix wrote:  See the {LOOPS_TEST_SET} class and the "symbolic_loop_tests" feature. -- You received this message because you are subscribed
