This morning on the old Caché Google Group, someone posed the following question, which I've decided to answer here, because it's interesting!

Is there a way to iterate ClassMethod's params, and get param's names and values?

The first answer I can come up with is: it's not easy! In any method, you could try to write code like this (where methodName is the name of your method):

REST and IO redirection

Problem: I have a REST broker, and if I hit a code block, which does IO redirection, the REST reply becomes broken in one of the following ways:

  • Binary output
  • No output
  • First 4096 characters of the reply are missing

Consider the following REST broker:

? %QUERY Wizard in VSCode ?

For my recent tutorial, I used %Query Wizard of Studio.

Could any of the VSCode experts please show me how to generate

Query Statement with input parameters, CONTAINID , ROWSPEC
and the required class methods
- <queryname>Execute()
- <queryname>Fetch()
- <queryname>Close()

I was just not able to do it.

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...

Mocking tools for Unit Testing

Hello everyone!

Does anyone know of a library that can be used to create Mock objects for Objectscript classes?

Right now, my team has been building mock objects by hand to help circumvent dependencies when writing and executing unit tests, but I always wondered if someone had ever created a Mock library like Mockito to help quicken the process.

Thanks!

Hello Everyone,

I'm want to know, what is more common for your company to use, the abbreviation syntax or the complety name of commands, and why?

Ex.

S VAR=10 / D FUNC^ROUTINE F 1:1:1000

Set VAR=10 / Do Func^Routine / For 1:1:1000

set var=10 / do func^routine / for 1:1:1000

Here in my company, we are familiar with the abbreviation syntax, because to spell is more faster.

If two globals have same structure, how to reuse one CacheSQLStorage-based class to read both locations?

Thanks!

Update:

Let's say we have two globals:

^a(1)="dataa1"
^a(2)="dataa2"

and

^b(1)="datab1"
^b(2)="datab2"

i.e. the structure difference is global name only.

I would like to have two classes TableA and TableB both are inherited from TableAB, and TableAB taking global name as a parameter.

Hi

Totally new to IRIS and Cache.

Trying to evaluate it and work out how we could use it.

As a standard application database. Object or relational etc. does not matter.

Issue is ObjectScript.

So:

1) Can we develop, maintain and use an IRIS database and never use ObjectScript i.e. use only Java, Python, C++ interfaces etc. (exactly which one does not matter)? Would that make designing and using the IRIS database more prone to inefficiency and error?

Testing OAuth2

I am attempting to setup my first OAuth2 client, as we are adventuring into the realm of making FHIR API calls to our EMR from HealthShare Health Connect.

I have gone through and set up the Issuer Endpoint, and Client Configuration but now I want to test it and verify that the setup is correct. When I setup the Client Configuration, it would not allow me to use Discovery as it was saying I needed a "Client secret" but was not given one. So I set it up manually, thinking I hit all the information correctly.

Scoping OID / OREF map

It's a feature of ObjectScript (perhaps widely known, perhaps not) that if you open the same object ID multiple times, you end up with the same OREF. For example:

USER>set obj1 = ##class(Sample.Person).%OpenId(1)
 
USER>set obj2 = ##class(Sample.Person).%OpenId(1)

USER>w obj1,!,obj2
1@Sample.Person
1@Sample.Person

Generally speaking, this is an important feature - you won't end up accidentally modifying the same record via multiple paths and losing some of the changes.

Hello,

Can anyone please provide me with a guide I can follow to create an entry in Cache's SSL/TLS configuration that would allow me to "speak" to an website via the Post method using SSL.

I need to simulate functionality that is provided by my browser but from with Cache.

The topics I have are:

1. From where do I source the certificate that will be used for this process?

2. What processing must I do on it to make it acceptable for Cache's SSL/TLS

3. What settings are required when filling the the form
