What does the `ordered` flag do in a to-many relationship?

为君一笑 提交于 2019-11-30 04:05:19
问题 While looking for ways to add an ordered to-many relationship to my Core Data model, with the least possible amount of changes to the model, I noticed an option of the to-many relationship that says ordered (see screenshot below). Wow, sounds great, but what does it do? My SQLite store is not complaining when I check or uncheck it, and my app still compiles and runs fine too. I was thinking maybe the lightweight migration takes care of the change, but from the looks of it, all my custom

Enum.HasFlag, why no Enum.SetFlag?

浪尽此生 提交于 2019-11-29 22:57:38
I have to build an extension method for each flag type I declare, like so: public static EventMessageScope SetFlag(this EventMessageScope flags, EventMessageScope flag, bool value) { if (value) flags |= flag; else flags &= ~flag; return flags; } Why isn't there an Enum.SetFlag like there is an Enum.HasFlag ? Also, why does this not work always? public static bool Get(this EventMessageScope flags, EventMessageScope flag) { return ((flags & flag) != 0); } For example, if I have: var flag = EventMessageScope.Private; And check it like: if(flag.Get(EventMessageScope.Public)) Where

How to disable a log.Logger

て烟熏妆下的殇ゞ 提交于 2019-11-29 22:12:21
I have some heavily instrumented code that makes use of the log package. Now it's come time to turn off the logging, and I can't determine how to turn off the standard logger. Have I missed something? Should I be checking a flag before making log calls, or commenting them out in production? Avinash R For completely disabling logs, it's actually better to call log.SetFlags(0) Joril and set the output to a no-op io.Writer (i.e., log.SetOutput(ioutil.Discard) ) But even after this, the operations will idle around 500-600 ns/op 1 This can still be cut short (to around 100 ns/op ) by using a custom

What happens if you set the flag on a PendingIntent to 0?

别来无恙 提交于 2019-11-29 18:20:49
问题 What exactly happens when you set the flag on a pending intent to 0? Does it just not raiise a flag or does it default to one of the others? 回答1: No this is the "default" behavior of creating a new PendingIntent regardless if one already exists or not. If you want more specialized behavior, like cancel an existing PendingIntent if the underlying Intent is the same, or update such an existing PendingIntent, then you should use the various flags you can find in the PendingIntent class. 来源:

Android: WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON question

不打扰是莪最后的温柔 提交于 2019-11-29 12:20:00
问题 Im using the following code to keep the screen on: this.getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); Is there any way to disable/remove the FLAG_KEEP_SCREEN_ON later in the code? (I want the screen to fadeout normally). Thanks! 回答1: You could probably do something like this this.getWindow().setFlags(this.getWindow().getFlags() & ~WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON) Did you look at the API? There's also this

WPF ComboBox/ListBox with MultiSelect based on Enum with Flags

醉酒当歌 提交于 2019-11-29 10:57:33
So I may be pushing the boundaries just a bit... Basically I have the following enum, declared in C# code: [Flags] public enum FlaggedEnum : int { Option1 = 1, Option2 = 2, Option3 = 4, Option4 = 8, ... Option16 = 32768, None = 0 } This enum is a member of an object which I have successfully bound to a DataGrid object. Successfully meaning that I have bound all the other fields successfully. :) What I want to achieve here is a control where all the appropriate options above are checked, that behaves and acts like a ComboBox/ListBox. So you click on the field and a drop-down menu pops up with

object editing and isDirty() flag

和自甴很熟 提交于 2019-11-29 10:27:18
I'm working on a system were a user can edit existing objects ("Filter" domain objects to be exact) through a GUI. As a UI hint, we only want to enable the save button if the user really modified something to the object. I was wondering if anyone had any experience with this problem and what the best way would be to approach this. I was thinking about adding an isDirty() flag to the domain object. When a user starts editing a Filter, I would then make a copy, pass it to the GUI and let the user make modifications to the copy. A binding on the isDirty() flag would then enabled/disable the save

App States with BOOL flags

余生长醉 提交于 2019-11-29 08:10:54
I've got 5 states in my app, and I use BOOL flags to mark them. But it isn't straightforward, because I have to write 5 lines to change all flags when I want to change state. Can you write some ideas or simple code to solve this problem? code: //need to choose second state flag1 = false; flag2 = true; flag3 = false; flag4 = false; flag5 = false; Also, it's to bad because I can choose 2 states one time. P.S. I found modern and more Apple-way. Answer below. Use typedef enum to define all possible states using bitmasks. Note this will give you a maximum of up to 64 different states (on most

How to get imap flags?

I used the imap4flag plugin for Dovecot sieve: http://wiki.dovecot.org/LDA/Sieve#Flagging_or_Highlighting_your_mail The flag is correctly show in thunderbird but I search how get the flags for show them in roundcube.
