You can apply the same change shown in the Index Settings example to all existing indices with one request, or even a subset of them: PUT /*/_settings { "index": { "indexing.slowlog.threshold.index.warn": "1s", "search.slowlog.threshold": { ...

Example uses basic HTTP syntax. Any <#> in the example should be removed when copying it. You can use the _cat APIs to get a human readable, tabular output for various reasons. GET /_cat/health <1> _cat/health has existed since Elasticsearch 1.x, but here is an example of its output...

Example uses basic HTTP syntax. Any <#> in the example should be removed when copying it. Like most _cat APIs in Elasticsearch, the API selectively responds with a default set of fields. However, other fields exist from the API if you want them: GET /_cat/health?help <1> ?help cau...

Example uses basic HTTP syntax. Any <#> in the example should be removed when copying it. The _cat APIs are often convenient for humans to get at-a-glance details about the cluster. But you frequently want consistently parseable output to use with software. In general, the JSON APIs are meant...

Input must must read from the Update function. Reference for all the available Keycode enum. 1. Reading key press with Input.GetKey: Input.GetKey will repeatedly return true while the user holds down the specified key. This can be used to repeatedly fire a weapon while holding the specified key ...

ANTLR is capable of generating parsers for a number of programming languages: C# Target Python Target JavaScript Target Java Target By default ANTLR will generate a parser from commandline in the Java programming language : Java -jar antlr-4.5.3-complete.jar yourGrammar.g4 //Will output a ...

First it's essential to understand that, game engines (such as Unity) work on a "frame based" paradigm. Code is executed during every frame. That includes Unity's own code, and your code. When thinking about frames, it's important to understand that there is absolutely no guarantee of w...

Often you design coroutines to naturally end when certain goals are met. IEnumerator TickFiveSeconds() { var wait = new WaitForSeconds(1f); int counter = 1; while(counter < 5) { Debug.Log("Tick"); counter++; yield return wait; } ...

import std.stdio; struct A { int b; void c(); string d; }; void main() { // The following foreach is unrolled in compile time foreach(name; __traits(allMembers, A)) { pragma(msg, name); } } The allMembers traits returns a tuple of string containing t...

First we need to set up two basic channels, one for the main queue, and one for the delay queue. In my example at the end, I include a couple of additional flags that are not required, but makes the code more reliable; such as confirm delivery, delivery_mode and durable. You can find more informatio...

Let's say, we have a simple LoginForm class with rules() method (used in login page as framework template): class LoginForm { public $email; public $rememberMe; public $password; /* rules() method returns an array with what each field has as a requirement. * Login form u...

All fragments should have an empty constructor (i.e. a constructor method having no input arguments). Therefore, in order to pass your data to the Fragment being created, you should use the setArguments() method. This methods gets a bundle, which you store your data in, and stores the Bundle in the ...

Dim Value As Double A Double is a signed 64 bit floating point data type. Like the Single, it is stored internally using a little-endian IEEE 754 memory layout and the same precautions regarding precision should be taken. A Double can store integer values in the range of -9,007,199,254,740,992 to...

Dim Value As Currency A Currency is a signed 64 bit floating point data type similar to a Double, but scaled by 10,000 to give greater precision to the 4 digits to the right of the decimal point. A Currency variable can store values from -922,337,203,685,477.5808 to 922,337,203,685,477.5807, givi...

Callbacks can be used to provide code to be executed after a method has completed: /** * @arg {Function} then continuation callback */ function doSomething(then) { console.log('Doing something'); then(); } // Do something, then execute callback to log 'done' doSomething(function () ...

If you want to delete rows (or columns) in a loop, you should always loop starting from the end of range and move back in every step. In case of using the code: Dim i As Long With Workbooks("Book1").Worksheets("Sheet1") For i = 1 To 4 If IsEmpty(.Cells(i, 1)) Then...

#Get the active Worksheet my $Book = $Excel->Activewindow; my $Sheet = $Book->Activesheet; #List of Worksheet names my @list_Sheet = map { $_->{'Name'} } (in $Book->{Worksheets}); #Access a given Worksheet my $Sheet = $Book->Worksheets($list_Sheet[0]); #Add new Worksheet...

#Edit the value of a cell (2 methods) $Sheet->Range("A1")->{Value} = 1234; $Sheet->Cells(1,1)->{Value} = 1234; #Edit the values in a range of cells $Sheet->Range("A8:C9")->{Value} = [[ undef, 'Xyzzy', 'Plugh' ], [ 42, 'Pe...

#Insert a row before/after line 22 $Sheet->Rows("22:22")->Insert(xlUp, xlFormatFromRightOrBelow); $Sheet->Rows("23:23")->Insert(-4121,0); #xlDown is -4121 and that xlFormatFromLeftOrAbove is 0 #Delete a row $Sheet->Rows("22:22")->Delete(); ...

In ui-router a state can hold multiple views, each with his own controller and a template .state('dashboard', { name: 'dashboard', url: '/dashboard', views: { "view1": { templateUrl: "path/to/view1.html", controller: "...
