Package com.yahoo.document
Class DocumentTypeManager
java.lang.Object
com.yahoo.document.DocumentTypeManager
The DocumentTypeManager keeps track of the document types registered in
the Vespa common repository.
The DocumentTypeManager is also responsible for registering a FieldValue factory for each data type a field can have. The Document object uses this factory to serialize and deserialize the various datatypes. The factory could also be used to expand the functionality of various datatypes, for instance displaying the data type in human-readable form or as XML.
