I'm trying to use PsiType.isAssignable method to find out the inheritance relationship between two classes.
However, all I have is two strings, each of them is fully qualified name of their respective classes.
Is there a way to create a PsiExpression and then get the PsiType out of it?
I did try to use expName.getType(), but it gave me NullPointerException.
Anyone can shed a light on this matter?
