NAME

       Lucy::Index::SegWriter - Write one segment of an index.

DESCRIPTION

       SegWriter is a conduit through which information fed to Indexer passes.  It manages
       Segment and Inverter, invokes the Analyzer chain, and feeds low level DataWriters such as
       PostingListWriter and DocWriter.

       The sub-components of a SegWriter are determined by Architecture.  DataWriter components
       which are added to the stack of writers via add_writer() have add_inverted_doc() invoked
       for each document supplied to SegWriter's add_doc().

METHODS

   add_doc( [labeled params] )
       Add a document to the segment.  Inverts "doc", increments the Segment's internal document
       id, then calls add_inverted_doc(), feeding all sub-writers.

   add_writer(writer)
       Add a DataWriter to the SegWriter's stack of writers.

   register( [labeled params] )
       Register a DataWriter component with the SegWriter.  (Note that registration simply makes
       the writer available via fetch(), so you may also want to call add_writer()).

       •   api - The name of the DataWriter api which "writer" implements.

       •   component - A DataWriter.

   fetch(api)
       Retrieve a registered component.

       •   api - The name of the DataWriter api which the component implements.
