SYNOPSIS¶

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

DESCRIPTION¶

METHODS¶

"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:

  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"
