PsiField is enum

Yes, that's how it's supposed to be done.

They've made it easier recently. Just use

field instanceof PsiEnumConstant

.

As far as I understand, this is a different thing. In the example provided
by Claus, 'EARTH' is a PsiEnumConstant, but 'from' is a regular PsiField.

You're right. I misunderstood.

Yeah I wasn't very easy to get from PsiField -> PsiClas.

I can't show the code as I am not connected to the internet at home where I work with the plugin. Here at work I can use the internet.

I remember I basically had to (pseudo code)

As you can see it's not easy and cumbersome. You manually have to check that the type isn't a simple type (int, char etc.). And this is also quite tricky.

I assume there is some code somewhere in IDEA that Jetbrains use to determine this, but it's not open.

Here's an easier way, but not very easy to discover if you don't know the api. This is one of those things that should be documented.

if (type instanceof PsiClassType) {
return false;
}

Of course you mean

if (!(type instanceof PsiClassType)) {
return false;
}

;)

Doh! That's what I meant.
