SYNOPSIS

 use RDF::Trine::Store::Memory;

DESCRIPTION

METHODS

"new ()"

Returns a new memory-backed 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 "Memory" 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 => 'Memory',
                  sources => [
                    {
                      file => 'test-23.ttl',
                      syntax => 'turtle',
                    },
                    {
                      url => 'http://www.kjetil.kjernsmo.net/foaf',
                      syntax => 'rdfxml',
                      graph => 'http://example.org/graph/remote-users'
                    }
                  ]
                });

"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_contexts"

Returns an RDF::Trine::Iterator over the RDF::Trine::Node objects comprising the set of contexts of the stored quads.

"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.

"count_statements ( $subject, $predicate, $object, $context )"

Returns a count of all the statements matching the specified subject, predicate, object, and context. Any of the arguments may be undef to match any value.

"etag"

If the store has the capability and knowledge to support caching, returns a persistent token that will remain consistent as long as the store's data doesn't change. This token is acceptable for use as an HTTP ETag.

"size"

Returns the number of statements in the store.

"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.
