Interface IEObjectDocumentationProviderExtension

All Known Implementing Classes:

MultiLineCommentDocumentationProvider

public interface IEObjectDocumentationProviderExtension

Allows to access the nodes that contain the documentation of an EObject and are considered by the IEObjectDocumentationProvider.

The custom documentation provider may use a list of syntax elements to compute the actual documentation string, e.g. C# style documentation like this

 /// First line
 /// second line
 

would return the documentation string

 First line
 second line
 

even though both lines are single line nodes.

The method getDocumentationNodes(EObject) allows to retrieve all nodes that contributed text to this documentation string. The primary use case is to be able to trace from the concrete source syntax to a possibly generated target file.

The default implementation MultiLineCommentDocumentationProvider uses only a single node, the closest multi line comment for a given EObject.
