Example 1 with BlockTreeNode

use of com.intellij.internal.psiView.formattingblocks.BlockTreeNode in project intellij-community by JetBrains.

the class PsiViewerDialog method initMap.

private void initMap(BlockTreeNode rootBlockNode, PsiElement psiEl) {
    JBTreeTraverser<BlockTreeNode> traverser = new JBTreeTraverser<>(o -> JBIterable.of(o.getChildren()));
    for (BlockTreeNode block : traverser.withRoot(rootBlockNode)) {

        }
        myPsiToBlockMap.put(currentElem, block);
        //nested PSI elements with same ranges will be mapped to one blockNode
        //    assert currentElem != null;      //for Scala-language plugin etc it can be null, because formatterBlocks is not instance of ASTBlock
        TextRange curTextRange = currentElem.getTextRange();
        PsiElement parentElem = currentElem.getParent();
        while (parentElem != null && parentElem.getTextRange().equals(curTextRange)) {
