# RDF::Trine::Store::Redland(3pm)

Redland-backed RDF store for RDF::Trine

## NAME

RDF::Trine::Store::Redland - Redland-backed RDF store for RDF::Trine

## VERSION

This document describes RDF::Trine::Store::Redland version 1.019

## SYNOPSIS

```
 use RDF::Trine::Store::Redland;
```

## DESCRIPTION

RDF::Trine::Store::Redland provides an RDF::Trine::Store interface to the Redland RDF store.

## METHODS

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

- "new ( $store )"

  Returns a new storage object using the supplied RDF::Redland::Model object.

- "new\_with\_config ( $hashref )"

  Returns a new storage object configured with a hashref with certain keys as arguments.

  The `"storetype"` key must be `"Redland"` for this backend.

  The following keys may also be used:

  - "store\_name"

    The name of the storage factory (currently `"hashes"`, `"mysql"`, `"memory"`, `"file"`, `"postgresql"`, `"sqlite"`, `"tstore"`, `"uri"` or `"virtuoso"`).

  - "name"

    The name of the storage.

  - "options"

    Any other options to be passed to RDF::Redland::Storage as a hashref.

- "new\_with\_object ( $redland\_model )"

  Initialize the store with a RDF::Redland::Model object.

- "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.

- "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.
