NAME

SWISH::Prog::Indexer - base indexer class

SYNOPSIS

 use SWISH::Prog::Indexer;
 my $indexer = SWISH::Prog::Indexer->new(
        invindex    => SWISH::Prog::InvIndex->new,
        config      => SWISH::Prog::Config->new,
        count       => 0,
        clobber     => 1,
        flush       => 10000,
        started     => time()
 );
 $indexer->start;
 for my $doc (@list_of_docs) {
    $indexer->process($doc);
 }
 $indexer->finish;

DESCRIPTION

SWISH::Prog::Indexer is a base class implementing the simplest of indexing APIs. It is intended to be subclassed, along with InvIndex, for each IR backend library.

METHODS

new( params )

Constructor. See the SYNOPSIS for default options.

params may include the following keys, each of which is also an accessor method:

clobber

Overrite any existing InvIndex.

config

A SWISH::Prog::Config object or file name.

flush

The number of indexed docs at which in-memory changes should be written to disk.

invindex

A SWISH::Prog::InvIndex object.

test_mode

Dry run mode, just prints info on stderr but does not build index.

init

Override base method to initialize object.

start

Opens the invindex() object and sets the started() time to time().

Subclasses should always call SUPER::start() if they override this method since it provides sanity checking on the InvIndex.

process( doc )

doc should be a SWISH::Prog::Doc-derived object.

process() should implement whatever the particular IR library API requires.

finish

Closes the invindex().

count

Returns the number of documents processed.

started

The time at which the Indexer object was created. Returns a Unix epoch integer.
