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.
