 The Structure View implementation used for a specific file type can be customized on many levels.
 If a custom language plugin provides an implementation of the [`StructureView`](upsource:///platform/editor-ui-api/src/com/intellij/ide/structureView/StructureView.java) interface, it can completely replace the standard structure view implementation with a custom user interface component.
 However, for most languages, this is not necessary, and the standard [`StructureView`](upsource:///platform/editor-ui-api/src/com/intellij/ide/structureView/StructureView.java) implementation provided by IntelliJ Platform can be reused.

+ > To modify an existing Structure View (e.g., add/filter nodes of builtin language support) , use [`StructureViewExtension`](upsource:///platform/structure-view-impl/src/com/intellij/ide/structureView/StructureViewExtension.java) registered in `com.intellij.lang.structureViewExtension` extension point.

 The starting point for the structure view is the [`PsiStructureViewFactory`](upsource:///platform/editor-ui-api/src/com/intellij/lang/PsiStructureViewFactory.java) interface, which is registered in the `com.intellij.lang.psiStructureViewFactory` extension point.
