NAME

Class::Indexed : An abstract class providing fine-grained and incremental update fulltext indexing for classes

SYNOPSIS

use Class::Indexed;

our @ISA = qw(Class::Indexed);

# build the index and metadata tables Class::Indexed->build_index_tables(database=>$db,host=>$host,username=>$user,password=>$password);

# set which attributes / fields are to be indexed and their weighting, etc $self->indexed_fields ( dbh=>$dbh, key=>'Pub_ID', fields=>[ { name=>'Pub_Name', weight=>1 }, ], );

# index an object $self->index_object();

# index a field or attribute of an object $self->index_field($self->{Pub_ID}, $field, $value);

# remove the object from the metadata and index tables $self->delete_location();

# add the object to the metadata table $self->add_location();

DESCRIPTION

This abstract class provides inherited indexing functionality to any class using it as a superclass.

Class::Indexed is designed to provide most of the functionality described in the article : 'Adding Search Functionality to Perl Applications' ( http://www.perl.com/pub/a/2003/09/25/searching.html ) and I recommend you read it through to gain understanding of the code and principles involved.

see the examples for the best explaination of how to use this class

EXPORT

None by default.

METHODS

build_index_tables

builds the index and metadata tables, you need to run this before you can use the indexing

my $success = Class::Indexed->build_index_tables(database=>$db,host=>$host,username=>$user,password=>$password);

index_object

indexes the object, updates the metadata if required

$self->index_object();

before you can call index_object you must set the fields to be indexed with the indexed_fields method

index_field

indexes a particular field or attribute of the object

$self->index_field($fieldname,$value)

takes the name of the attribute/field and the new value

before you can call index_field you must set the fields to be indexed with the indexed_fields method

delete_location

remove the object from the metadata and index tables

$self->delete_location();

add_location

add the object to the metadata table

$self->add_location();

indexed_fields

set which attributes / fields are to be indexed and their weighting, etc $self->indexed_fields ( dbh=>$dbh, key=>'Pub_ID', fields=>[ { name=>'Pub_Name', weight=>1 }, ], );
