I'm trying to create a method that will automatically create something I can save and use later, which will let me automate data migration from one version of a class to the next.
We are trying to create a simple class extending %RegisteredObject that could be used as a singleton. However we are not able to store it in a global to later be retrieved (by the same process but elsewhere in the code).
I want to add a class to my project. This class is in UDL format.
I know that there is a method: ##class(%Compiler.UDL.TextServices).SetTextFromStream. The problem is that to use this method I need to know the name of the class (including all packages) in advance. But, a class can have any name(I mean C:/source/AAA/BBB/CCC.cls, but the real name is Sample.Human.cls).
For now I found only one way to get to know the name of a class - just parse the class code and search for a word which is followed by "Class" word. Is there any better way to do that?
Would like to know if there is an alternative or better way to paginate through a dataset using dynamic SQL than what I am using below. The problem is that as the potential pool of data gets larger, this code slows down to the point of not being useable. In analyzing each line of code below, it appears the slow down is related to the initial rset.%Next() iteration. Is there anything available which does not require a subquery/%VID such as a simple LIMIT/OFFSET?
I created the Process to extract the required data from ADT message to a Dynamic Object. I wanted to send the JSON stream to EnsLib.File.PassthroughOperation operation and generate a file with the content of JSON stream.
Recently I came across a very strong statement to the effect that InterSystems.Data.CacheClient.dll library works fast because it does not open a TCP/IP connection, instead it works in the same process as a database. It made me pause for quite some time. Firstly because .Net Managed Provider, which utilises this library, opens TCP/IP connection to the database (and it is stated in the documentation "Using .NET and the ADO.NET Managed Provider with Caché"). And secondly, because as far as I know only eXtreme applications attach themselves to the process.
I am trying to come up with a way to decode the Base64 we receive in an HL7 message into a PDF file and save it in a directory on our AIX machine. I thought I had the following working at one time but I am having issues. Has anyone done this before?
I have a class to track data changes. As it becomes slower and slower to find last changes I think I need an index. The 2 classes are just simplified reality. HowTo ?
Class Rick.ChangeItem Extends %SerialObject { Property Subject As %String;
Let's say the user need to execute some heavy code (build a report, or extensive calculations etc.). So, of course it needs to be asynchronous, and we possibly need to store some data about execution status. How?
I am still a beginner with COS and am struggling with these concepts. While digging through the official documentation will eventually tell you everything you need to know, getting started is nevertheless not an easy feat...
Is it possible to create a "lists/array/multidimensional 101" page for beginners? And, for instance, its interaction with $data, what it means to use "as list of something" or "as array of something", how to walk lists, how to add/remove elements, how to extract sublists etc?
I would like to integrate SQL into our ObjectScript routines in order to illustrate how SQL can be used to minimize development time. However, there are two questions I have.
How does one iterate through the results of a SELECT statement?
I need submit a object have a json string as property of class, but I get an issue, object can't save to SQL table if I take json data to json property. I try making a test class with only json property and get the same issue, no data row in SQL table after run ClassMethod . Some one know what's problem, please help me. Here my test class:
What I have is a criteria how to select "my" strings. What I need is to replace all of them with macro calls (using the same strings as arguments) in all classes of current namespace.
I was ready to write straightforward code, but at the last moment decided to ask the community: maybe I've overlooked a smarter option?
Any comments and advices would be great appreciated.
Good morning people. The use of TDD is currently being reference for software delivery more confiabilitade and quality.
At the company I work developing web applications , we create tests for method class in a deteminado package and running the steps that the documentation recommends:
1 export the tests classes to a predefined folder. 2- And running the test ( D ## class (% UnitTest.Manager ) .RunTest (,"/nodelete" )
It is a lot of work to do the export and run these tests would have a resource that we could only run the tests without the need for export ?
I was writing a routine that called some class methods and when I typed in ##class( and the package, there was a drop down list of all the classes that match that package but when I selected one of the dropdown entries it added the package name again.
For example if I enter ##class(dim.
I am presented with a list of classes in the dim package but when I selected one of them,(dim.OccupationList), what ended up in the editor was
I have a non objectscript application connecting to a cache instance via ODBC and one column is a list of serial objects. The output from the query contains a lot of special characters and I'm hoping there's a better way to get this data back so I won't have to perform extensive parsing on the application side.
I've tried using the $ListToString() function, but that didn't help much, probably because the list contains complex objects rather than primitives.
