Examples of com.intellij.psi.PsiReference

com.intellij.psi.PsiReference
A reference to a PSI element. For example, the variable name used in an expression. The "Go to Declaration" action can be used to go from a reference to the element it references. @see PsiElement#getReference() @see PsiElement#getReferences()
