public interface IImporterHandler

Identifies a class as being an import handler. Handlers performs specific tasks on the importing content (other than parsing to extract raw content). They can be invoked before or after a document is parsed. There are four types of handlers currently supported:

• IDocumentFilter: accepts or reject an incoming document.
• IDocumentTagger: modifies a document metadata.
• IDocumentTransformer: modifies a document content.
• IDocumentSplitter: splits a document into multiple ones.
