[Plugin][Code Intention] Get PsiType of Class to the left of user's cursor

TL;DR: Given the PsiElement passed to IntentionAction#isAvailable, how do I get PsiType for what *might* be a Class to the left of the user's cursor ?

Consider the following piece of code:

import com.fake.package.FooBar;

public void fakeMethod() {
    FooBar|
}

Imagine that there is a class FooBar and the user's cursor is placed at the end of FooBar in the above code snippet (i.e. where I have placed | ). I am developing a Code Intention that requires I have a PsiType instance for FooBar (i.e. the class directly to the left of the user's cursor if it is indeed a class -- if it's not a class the Intention Action won't be available).

Where I am currently stuck is using the PsiElement given to IntentionAction#isAvailable(...) to get an instance of PsiType representing FooBar.

Here's what I've got so far (where elementAtCursor is the PsiElement passed to IntentionAction#isAvailable(..))

PsiElement elementLeftOfCursor = elementAtCursor.getPrevSibling();
PsiReferenceExpression referenceExpression =
        (elementLeftOfCursor instanceof PsiReferenceExpression) ?
        (PsiReferenceExpression) elementLeftOfCusor :
        PsiTreeUtil.findChildOfType(elementLeftOfCursor, PsiReferenceExpression.class);

This gives me an instance of PsiReferenceExpression that points to FooBar but I'm unsure of how to go from that to PsiType for FooBar... I imagine I must use the Class' import statements somehow and match to this reference expression.

Any tips here? I can't seem to figure out how to use the class' import statements to retrieve the PsiType here.
