NAME

       Lucy::Index::DataReader - Abstract base class for reading index data.

SYNOPSIS

           # Abstract base class.

DESCRIPTION

       DataReader is the companion class to DataWriter.  Every index component will implement one
       of each.

CONSTRUCTORS

   new( [labeled params] )
           my $reader = MyDataReader->new(
               schema   => $seg_reader->get_schema,      # default undef
               folder   => $seg_reader->get_folder,      # default undef
               snapshot => $seg_reader->get_snapshot,    # default undef
               segments => $seg_reader->get_segments,    # default undef
               seg_tick => $seg_reader->get_seg_tick,    # default -1
           );

       ·   schema - A Schema.

       ·   folder - A Folder.

       ·   snapshot - A Snapshot.

       ·   segments - An array of Segments.

       ·   seg_tick - The array index of the Segment object within the "segments" array that this
           particular DataReader is assigned to, if any.  A value of -1 indicates that no Segment
           should be assigned.

ABSTRACT METHODS

       if such a reader is not valid.

       ·   offsets - Doc id start offsets for each reader.
