Detailed Description

Main service for accessing the MICO persistence API.

The persistence service can be used for managing ContentItems stored in the peristence API of the MICO platform. Services working with ContentItems should only use instances of this class for accessing the persistence API.

Constructor & Destructor Documentation

mico::persistence::PersistenceService::PersistenceService	(	std::string	marmottaServerUrl,
		std::string	contentDirectory
	)

Initialise an instance of the PersistenceService using the Marmotta server with the given URL as backend.

Parameters

marmottaServerUrl

the URL of the Apache Marmotta server, e.g. http://localhost:8080/marmotta

Member Function Documentation

std::shared_ptr< model::Item > mico::persistence::PersistenceService::createItem

(

)

Create a new content item with a random URI and return it.

Create a new item with a random URI and return it.

The content item should be suitable for reading and updating and write all updates to the underlying low-level persistence layer.

Returns

a handle to the newly created ContentItem

The item should be suitable for reading and updating and write all updates to the underlying low-level persistence layer.

Returns

a handle to the newly created Item

void mico::persistence::PersistenceService::deleteItem

(

const mico::persistence::model::URI &

id

)

Delete the content item with the given URI.

If the content item does not exist, do nothing.

jnipp::LocalRef< Anno4j > mico::persistence::PersistenceService::getAnno4j

(

)

Return an iterator over all currently available content items.

Returns

iterable Return the end iterator for checking when iteration has completed.

iterable

std::shared_ptr< model::Item > mico::persistence::PersistenceService::getItem

(

const mico::persistence::model::URI &

id

)

Return the item with the given URI if it exists.

The item should be suitable for reading and updating and write all updates to the underlying low-level persistence layer.

Returns

A handle to the Item with the given URI, or null if it does not exist

std::vector< std::shared_ptr< model::Item > > mico::persistence::PersistenceService::getItems

(

)

Get all items of the persistence service connection Notice that this implementation might be rather slow since it fetches all items first and then creates new ItemMMM object out of it.

Returns

A std::vector<Item>

PersistenceMetadata& mico::persistence::PersistenceService::getMetadata ( )

inline

Get a handle on the overall metadata storage of the persistence service.

This can e.g. be used for querying about existing content items.

Returns
