If I were trying to access an index of a global variable, what time complexity would this operation have? My understanding of languages like Java/C++ is that arrays are stored as blocks of memory so that x[15] would have a lookup time complexity of O(1) because it just goes to (address of the array + 15) and retrieves the value stored there.

How does this work in Cache where the index of a variable isn't necessarily an integer value? If I were to have a variable like the following:

x("Adam") = "Red"

x("George") = "Blue"

x("Bryan") = "Green"

etc...

Hi,

The class %JSON.Adaptor is very convenient,

I wonder if anyone faced the following scenario using it-

Exporting an object, that has a many to many relationship, and getting the details of the related objects.

For example, if we have three classes - Teachers, Students, and an intermediate class TeacherStudent .

The classes extend %JSON.Adaptor, and we would like to open a Student object, use %JSONExport, and get a JSON

That includes the details of the student and all the teachers that teach the student, something like:

Hello, this is going to be a stupid question, yea I know, there are no stupid questions.

Say, I have an Object Property, Name or Count or Title, or whatever.

How can I get a list, or find out all the different ways it can be expressed?

Example:

-Property Name As %Name;

-Property Name As %String="me"

-Property Name As %String [ Required];

But what other parameters, keywords, restrictions, lists, etc. that I can apply to this Property?

Is the default language (i.e., $$$DefaultLanguage, which is used as the basis for localization with $$$Text/etc. at compile time) always "en" for new Caché installations, or could it be different? How is this determined? I don't see an option to select a language during Caché installation.

Also, is there a supported/preferred API for setting the default language? Looking at %occMessages.inc, one option would be:

Remove deleted classes after import

When you deploy code from a repo, class (file) deletion might not be reflected by your CICD system.
Here's a simple one-liner to automatically delete all classes in a specified package that have not been imported. It can be easily adjusted for a variety of adjunct tasks:

set packages = "USER.*,MyCustomPackage.*"
set dir = "C:\InterSystems\src\"
set sc = $SYSTEM.OBJ.LoadDir(dir,"ck", .err, 1, .loaded)
set sc = $SYSTEM.OBJ.Delete(packages _ ",'" _ $LTS($LI($LFS(loaded_",",".cls,"), 1, *-1), ",'"), "/generated=0", .err2)

The first command compiles classes and also returns a list of loaded classes. The second command deletes all classes from specified packages, except for the classes loaded just before that. Any generated classes are also skipped since they won't be in the loaded list.

I have started working on utilizing Epic on FHIR about a month ago.

Creating a Public Private Key Pair

mkdir /home/ec2-user/path_to_key
openssl genrsa -out ./path_to_key/privatekey.pem 2048

For backend apps, you can export the public key to a base64 encoded X.509 certificate named publickey509.pem using this command...

Hi,

When wanting to use VS-Code for server-side editing.. - In VS-code I can right click on a server item (eg a class) to see a set of menu options including 'Server Source Control... ' and 'Server Command Menu...' at the bottom.

I noticed that these options are somewhat connected to my server-side source control hooks class that inherits from %Studio.SourceControl.Base, however, I am seeing different behavior between my custom subclass of this, and, the provided %Atelier.SourceControl subclass.

Hello Everyone,

I was wondering about the best way to initialize several variables, or several lists of variables.

Would it be better to write it like:

set (var1, var2, var3) = "value1"
set (var4, var5) = "value2"
set (var6,var7,var8) = "value3"

or

set var1="value1", var2="value1", var3="value1", var4="value2", var5="value2", var6="value3", var7="value3", var8="value3"

or

Hello, I'm new to Ensemble, and my first task is to become familiar with the Production and create a basic outline of it for the users to view (which servers, where are the input files, where are the output files, how many records...). What are the Production tables? I'd like to start there.

Thanks,

Laura

I'm attempting a first-time installation of IRIS for Health on my home Mac for eval purposes. I want to be able to install IRIS and Ensemble. I downloaded the package but it doesn't come with instructions, and I'm running into issues. Is there a straightforward install instruction set online, or does anyone have one you can pass along?

Thanks, Jim Winski

Hi all,

a HealthConnect customer of ours came across with a question to use an external service via REST and OpenID within one of his HealthConnect (2020.1) productions. The overal idea is to send data to the external system after receiving a baerer token to use for the communication between HealthConnect and this system.
