I need to check if one class is a subclass of another (either direct or indirect).

For example:

Class Package.ClassA Extends %Library.Persistent
{
}

Class Package.ClassB Extends Package.ClassA 
{
}

Class Package.ClassC Extends Package.ClassB
{
}

In this example Package.ClassC is a subclass of 3 classes: %Library.Persistent, Package.ClassA, Package.ClassB.

So any of these checks should return 1:

0 3
0 757

I need to get a list of all classes that are subclasses of two unrelated classes.

For example I want to get a list of all classes that are both:

  • Persistent (extends %Library.Persistent)
  • XML-Enabled (extends %XML.Adaptor)

To get subclasses of one class I can use this query:

set rs = ##class(%Dictionary.ClassDefinitionQuery).SubclassOfFunc("%Library.Persistent")

But what about two classes?

I'm trying to create asynchronous Ensemble service/operation pair for SOAP passthrough.

General configuration:

  • Ensemble Service receives a message and immediately returns an answer to a caller (message received or some error)
  • Ensemble Service asynchronously calls Business Operation
  • Business Operation does guaranteed message delivery, etc.

Is it a viable approach?

Any tips? Ideas? Caveats? Code?

Seems like I can sublass EnsLib.SOAP.GenericService and change Sync to ASync (and provide a default reply immediately).

Hi, Community!

And so I continue with publishing of the tasks for the Final round of InterSystems Contest on InterSystems Caché and DeepSee as a part of IT Planet Student Championship in Sochi. This year we had about 2 000 participants in InterSystems Contest.

One of the tasks for the finals was to crack the black box and another to output 9876543210!

Here's the next task: gravity!

I'm using %SOAP.WebRequest to send SOAP requests:

  1. Populate %SOAP.WebRequest object (by setting Request and HeadersOut properties)
  2. Call SendSOAPBody method to send request

Currently the XML I send looks like this:

<?xml version="1.0" encoding="UTF-8" ?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV='http://schemas.xmlsoap.org/soap/envelope/'>
  <SOAP-ENV:Header>
<SomeCustomHeader/>  </SOAP-ENV:Header>
  <SOAP-ENV:Body><SomeCustomBody/></SOAP-ENV:Body>
</SOAP-ENV:Envelope>

However, I want XML to be generated differently:

  • No new lines
  • No whitespaces between <SomeCustomHeader/> and </SOAP-ENV:Header>

How can I tweak XML generation to achieve that?

How do I write DDL script for collection properties?

For example I want to create the following class:

Class SQLUser.Person {

Property Name As %String;

Property FavoriteColors As list Of %String;

}

My DDL script looks like this:

CREATE TABLE Person (Name varchar(50), FavoriteColors ???)
0 4
0 355

I'm aware of two ways to get list of files in a dir:

set dir = "C:\temp\"
set rs = ##class(%File).FileSetFunc(dir, , , 1)
do rs.%Display()

and:

set dir = "C:\temp\"
set file=$ZSEARCH(dir_"*")
while file'="" {
   write !,file
   set file=$ZSEARCH("")
}

Yet they bot return only files and directories in a current directory, but not files in subdirectories.

I suppose I call one of these recursively, but maybe there's a better solution?

Debugging Web

In this article I'll cover testing and debugging Caché web applications (mainly REST) with external tools. Second part covers Caché tools.

You wrote server-side code and want to test it from a client or already have a web application and it doesn't work. Here comes debugging. In this article I'll go from the easiest to use tools (browser) to the most comprehensive (packet analyzer), but first let's talk a little about most common errors and how they can be resolved.
