Is

new HashMap() {{ put("this", true) }};

==

mapOf("this" to true)

(note the double

{{

)?

yes, should be

Thanks for confirmation!

Don't do

{{ }}

in frequently executed code. Each time anonymous class is created, in the days of PermGenSpace this would kill a lot of apps, nowdays it will probably just cause a slow growing memory hog which could potentially cause OutOfMemory error down the line. I think

{{ }}

should only be allowed during app initialization (which would ensure that only finite number of anonymous classes are generated) and nowhere else.

I was assuming the OP wanted to use

mapOf(...)

instead; at least, I hope so 😉

Yup, looks like it, but I got burned on double braces at some point in my professional life, so I can't be silent 😄

Right, I want mapOf instread, but in the odoo xmlrpc docs, they have that for the java example...
