KinoSearch::Index::DataWriter - Write data to an index.
The KinoSearch code base has been assimilated by the Apache Lucy project. The "KinoSearch" namespace has been deprecated, but development continues under our new name at our new home: http://lucy.apache.org/
# Abstract base class.
DataWriter is an abstract base class for writing index data, generally in segment-sized chunks. Each component of an index -- e.g. stored fields, lexicon, postings, deletions -- is represented by a DataWriter/DataReader pair.
Components may be specified per index by subclassing Architecture.
my $writer = MyDataWriter->new( snapshot => $snapshot, # required segment => $segment, # required polyreader => $polyreader, # required );
Process a document, previously inverted by
Add content from an existing segment into the one currently being written.
Complete the segment: close all streams, store metadata, etc.
Every writer must specify a file format revision number, which should increment each time the format changes. Responsibility for revision checking is left to the companion DataReader.
Remove a segment's data. The default implementation is a no-op, as all files within the segment directory will be automatically deleted. Subclasses which manage their own files outside of the segment system should override this method and use it as a trigger for cleaning up obsolete data.
Move content from an existing segment into the one currently being written.
The default implementation calls add_segment() then delete_segment().
Arbitrary metadata to be serialized and stored by the Segment. The default implementation supplies a Hash with a single key-value pair for "format".
