Class GreedyTikaField

java.lang.Object
  it.unimi.di.mg4j.document.tika.TikaField
      it.unimi.di.mg4j.document.tika.GreedyTikaField

All Implemented Interfaces:

Serializable

public class GreedyTikaField
extends TikaField

The set of all Tika metadata represented as a single field inside MG4J.

When using an AutoDetectDocumentFactory or any other factory in which metadata fields are user-definable or otherwise variable, it is impossible to provide a static listing of all available fields, as they depend on the actual factory used to parse the document. In this case, an instance of this class is used to return some useful data to the caller.
