RDF::Trine::Store::HexUserrContributed Perl DocRDF::Trine::Store::Hexastore(3)

NAME
       RDF::Trine::Store::Hexastore - RDF store	implemented with the hexastore
       index

VERSION
       This document describes RDF::Trine::Store::Hexastore version 1.019

SYNOPSIS
	use RDF::Trine::Store::Hexastore;

DESCRIPTION
       RDF::Trine::Store::Hexastore provides an	in-memory triple-store based
       on six-way indexing as popularized by Hexastore.

METHODS
       Beyond the methods documented below, this class inherits	methods	from
       the RDF::Trine::Store class.

       "new ()"
	   Returns a new storage object.

       "new_with_config	( $hashref )"
	   Returns a new storage object	configured with	a hashref with certain
	   keys	as arguments.

	   The "storetype" key must be "Hexastore" for this backend.

	   This	module also supports initializing the store from a file	or
	   URL,	in which case, a "sources" key may be used. This holds an
	   arrayref of hashrefs.  To load a file, you may give the file	name
	   with	a "file" key in	the hashref, and to load a URL,	use "url". See
	   example below. Furthermore, the following keys may be used:

	   "syntax"
	       The syntax of the parsed	file or	URL.

	   "base_uri"
	       The base	URI to be used for a parsed file.

	   The following example initializes a Hexastore store based on	a
	   local file and a remote URL:

	     my	$store = RDF::Trine::Store->new_with_config( {
		 storetype => 'Hexastore',
		 sources => [
		     {
			 file => 'test-23.ttl',
			 syntax	=> 'turtle',
		     },
		     {
			 url =>	'http://www.kjetil.kjernsmo.net/foaf',
			 syntax	=> 'rdfxml',
		     }
	     ]});

       "store (	$filename )"
	   Write the triples data to a file specified by $filename.  This data
	   may be read back in with the	"load" method.

       "load ( $filename )"
	   Returns a new Hexastore object with triples data from the specified
	   file.

       "temporary_store"
	   Returns a temporary (empty) triple store.

       "get_statements ($subject, $predicate, $object [, $context] )"
	   Returns a stream object of all statements matching the specified
	   subject, predicate and objects. Any of the arguments	may be undef
	   to match any	value.

       "get_pattern ( $bgp [, $context]	)"
	   Returns a stream object of all bindings matching the	specified
	   graph pattern.

       "supports ( [ $feature ]	)"
	   If $feature is specified, returns true if the feature is supported
	   by the store, false otherwise. If $feature is not specified,
	   returns a list of supported features.

       "get_contexts"
       "add_statement (	$statement [, $context]	)"
	   Adds	the specified $statement to the	underlying model.

       "remove_statement ( $statement [, $context])"
	   Removes the specified $statement from the underlying	model.

       "remove_statements ( $subject, $predicate, $object [, $context])"
	   Removes the specified $statement from the underlying	model.

       "etag"
	   Returns an Etag suitable for	use in an HTTP Header.

       "nuke"
	   Permanently removes all the data in the store.

       "count_statements ($subject, $predicate,	$object)"
	   Returns a count of all the statements matching the specified
	   subject, predicate and objects. Any of the arguments	may be undef
	   to match any	value.
