Class FoldingModelSupport

java.lang.Object

com.intellij.diff.tools.util.FoldingModelSupport

Direct Known Subclasses:

ThreesideTextDiffViewerEx.MyFoldingModel

public class FoldingModelSupport
extends java.lang.Object

This class allows to add custom foldings to hide unchanged regions in diff. EditorSettings#isAutoCodeFoldingEnabled() should be true, to avoid collisions with language-specific foldings (as it's impossible to create partially overlapped folding regions)

DiffUtil.setFoldingModelSupport(EditorEx)
