PsiElement currentElement = // current element in the abstract syntax tree PsiElement parentElement = currentElement.getParent(); if (parentElement instanceof PsiMethod) { // do something with the method containing the current element }
PsiElement currentElement = // current element in the abstract syntax tree while (currentElement != null) { PsiElement parentElement = currentElement.getParent(); // do something with the parent element currentElement = parentElement; }In this example, we use getParent to continuously navigate up the abstract syntax tree, performing some logic on each parent element until there are no more parent elements (i.e., the top of the tree has been reached). The com.intellij.psi package is a library within the IntelliJ IDEA development environment, used for working with the abstract syntax tree of source code files.
