Interface INodeVisitor

Visitor interface for all types of filter framework editor specific nodes.

Namespace: SdlSdl.DesktopEditorEditorApi
Assembly: Sdl.DesktopEditor.EditorApi.dll
Syntax
public interface INodeVisitor
Remarks

To take advantage of the visitor pattern, create a visitor class that implements this interface, instantiate an object, and pass it to AcceptNodeVisitor(INodeVisitor) on any INode instance.

The node will call back on the function in this interface that corresponds to its type.

This mechanism is very useful to avoid large switch/if/else tests for node types when processing nodes from collections (e.g. node containers). Not only do you avoid having to write these complex switches, the compiler will also tell you if the interface has been extended with new node types. That makes keeping the functionality up-to-date when the editor evolves much easier.
