Vuex - passing multiple parameters to mutation
(3 answers)
Closed 3 years ago.
Looking at docs
https://vuex.vuejs.org/guide/actions.html
vuejs 2.6 / vuex,3.0.1
do not see if actions can be dispatched with 1 more parameter, as on all these examples?
I tried to dispatch action with 2 parameters, but the second was undefined in action...
Nope you need to dispatch an object with a few fields, if you want a number of parameters.

whats syntax for calling other scenario in same feature file?
(1 answer)
Closed 1 year ago.
demoType is a variable and I want the content of this variable to be what is evaluated in the following expression:
* def call read(demoType)
On the contrary, it tries to evaluate the name of the variable and not its content.
There is no such thing as def call.
Maybe you were trying:
* call read(demoType)
Or:
* def temp = call read(demoType)
Make sure you are on the latest version of Karate. And read the docs: https://github.com/intuit/karate#call-vs-read

ArrayList<String>() vs arrayListOf<String>()
(5 answers)
Closed 3 years ago.
I searched the difference between arrayListOf and ArrayList.
so I understand arrayListOf is function, and ArrayList is class.
but I don't understand the exact difference using them.
As described in the documentation arrayListOf is a function that creates an ArrayList instance. If I understand it correctly it serves the purpose of determining the generic type from the passed input values and it's a convenience function.

Access variables and functions defined in page context using a content script
(6 answers)
Closed 7 years ago.
How can I inject a <script> to my document which will initialize a variable?
content_script:
$("body").append('<script type="text/javascript">myvar="hi there";</script>');
When I do this, the variable myvar is not recognized...
If I add a simple alert(500); I get the alert.
Basically I just want to pass a variable from the extension the document to use it there.
add var
$("body").append('<script type="text/javascript">var myvar="hi there";</script>');

Caret in objective C

What does ^ character in Objective C mean? like in the following code
TWTweetComposeViewControllerCompletionHandler
completionHandler =
^(TWTweetComposeViewControllerResult result) {
switch (result)
{
...
}
[self dismissModalViewControllerAnimated:YES];
};
It denotes a "block", a piece of code that can be packaged into an object and used later. In your example it specifies a completion handler to be called later, presumably when the user clicks "OK" or some similar button to close an alert.
Blocks can also be used with Grand Central Dispatch and in that case they are used to produce a unit of code that can be run on another thread, both synchronously and asynchronously.
This is a "block", you can read about this in the Apple-Developer-doc, it's mainly used for Multithreading.
It's used as part of the definition of a block:
^(return_type retval) {
statements;
}
You'll see it as part of declarations of blocks too.

Method overloading in Objective-C?
Is method overloading not possible.
I have two functions with the same name.
When declared like the below i'm etting errors.
-(RS232Msg*)CreateMessage:(REMOTE_MESSAGE_ID) nMessageNumber;
-(RS232Msg*)CreateMessage:(const uint8_t*) szMessageName;
when declared -(RS232Msg*)CreateMessage:(const uint8_t*) szMessageName; i'm not getting any errors.
I also have two functions as the same name with different return type and argument.But its working fine and there is no error in its declaration.
Why is it so?
No, method overloading is not possible in C, and therefore not possible in Objective-C (since Objective-C is a superset of C). If you'd like to use those two methods, you'll have to change their names. I would suggest the following:
- (RS232Msg *)createMessageWithMessageID:(REMOTE_MESSAGE_ID)nMessageNumber;
- (RS232Msg *)createMessageWithName:(const uint8_t*)szMessageName;
