Interface TextExtractorMap

All Known Implementing Classes:

TextExtractorMapSet

public interface TextExtractorMap

Given a Jena resource, a ValueExtractor can derive zero or more String representations. The returned value is a map between the key (e.g. where it is extracted from like label or fragment etc) and the corresponding texts. Developer remark: If you implement a new extractor: For a good design, you may want to implement a LiteralExtractorMap and use this interface to wrap it.
