NAME¶
AtteanX::Store::Memory - Simple in-memory RDF store
VERSION¶
This document describes AtteanX::Store::Memory version 0.002
SYNOPSIS¶
use AtteanX::Store::Memory;
DESCRIPTION¶
AtteanX::Store::Memory provides an in-memory quad-store.
METHODS¶
Beyond the methods documented below, this class inherits methods from the
Attean::API::QuadStore class.
- "new ()"
- Returns a new memory-backed storage object.
- "size"
- Returns the number of quads in the store.
- "get_quads ( $subject, $predicate, $object, $graph )"
- 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_graphs"
- Returns an iterator over the Attean::API::Term objects comprising the set
of graphs of the stored quads.
- "add_quad ( $quad )"
- Adds the specified $quad to the underlying model.
- "remove_quad ( $statement )"
- Removes the specified $statement from the underlying model.
- "remove_quads ( $subject, $predicate, $object, $graph )"
- Removes the specified $statement from the underlying model.
- "create_graph( $graph )"
- This is a no-op function for the memory quad-store.
- "drop_graph( $graph )"
- Removes all quads with the given $graph.
- "clear_graph( $graph )"
- Removes all quads with the given $graph.
- "count_quads ( $subject, $predicate, $object, $graph )"
- Returns a count of all the statements matching the specified subject,
predicate, object, and graph. Any of the arguments may be undef to match
any value.
- "etag_value_for_quads"
- 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.
