IDocumentVisitor Interface

Interface implementing the Visitor pattern.

Namespace: DevExpress.XtraRichEdit.API.Native

Assembly: DevExpress.RichEdit.v20.2.Core.dll


public interface IDocumentVisitor


The Visitor pattern allows you to create a separate visitor concrete class for each type of operation, and to separate this operation implementation from the objects structure. Refer to the How to: Retrieve the List of Document Fonts using the Visitor-Iterator Pattern topic for more details.


The DocumentVisitorBase class implements the IDocumentVisitor interface by default. Since the interface’s implementation can be modified, we recommend using the DocumentVisitorBase class instead creating of your own to avoid compile-time errors.

The following code snippets (auto-collected from DevExpress Examples) contain references to the IDocumentVisitor interface.


The algorithm used to collect these code examples remains a work in progress. Accordingly, the links and snippets below may produce inaccurate results. If you encounter an issue with code examples below, please use the feedback form on this page to report the issue.
