NAME
       RDF::Trine::Store::Memory - Simple in-memory RDF store

VERSION
       This document describes RDF::Trine::Store::Memory version 1.000

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

DESCRIPTION
       RDF::Trine::Store::Memory provides an in-memory triple-store.

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

       "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:

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

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

	   "graph" NOT IMPLEMENTED
	       Use this URI as a graph name for the contents of the file or URL.

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

	     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.
