NAME

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

VERSION

       This document describes RDF::Trine::Store::Hexastore version 1.000

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.
