Under Intersystems Property Keywords documentation Aliases is not listed as a keyword. However, in studio if I type

Property Tst As %String [

the drop-down pops up with Aliases and fills it with

Property Tst As %String [ Aliases =

The only way I got it to compile is

Aliases = { "some value?" } ];

So, how is Aliases used?

UPDATE: I know I did this backwards, found a feature then looked for a problem, but I found a use-case. If you are an ensemble user, the message viewer only displays the message if its "valid"ish xml, i.e. no spaces in the xml tag names. However your object has to have space in the property name,

Property "Due Date?" As %String;

you can do the following

Property "DueDate" As %String [ Aliases = {Due Date} ];

and still reference the property by the old name obj."Due Date?", allowing the message to show up in the viewer and keeping the old "vernacular'.

EDIT: it actually does work, but the syntax is 

Property Name As %String [ Aliases = {name2} ];

So, no quotes.

What are you trying to achieve here?

  • Curiosity, Ok so, I was setting ```Aliases = { another property }``` and that wasn't doing anything, I changed it up to ```{ some name that doesn't exist }``` and then I could reference it by both names – jtzero Jun 04 '14 at 15:44

I think it is not used at all. Because have no any reference in documentation or in code about it.
