Class TreeAnchorizer

java.lang.Object

com.intellij.ide.util.treeView.TreeAnchorizer

Direct Known Subclasses:

PsiTreeAnchorizer

public class TreeAnchorizer
extends java.lang.Object

Used by UI trees to get a more memory-efficient representation of their user objects. For example, instead of holding PsiElement's they can hold PsiAnchor's which don't hold AST, document text, etc. This service is used to perform object<->anchor conversion automatically so that all 100500 tree nodes don't have to do this themselves.
