NAME

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

DEPRECATED

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/

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

aggregator( [labeled params] )

Create a reader which aggregates the output of several lower level readers. Return undef if such a reader is not valid.
