Member Function Documentation

bool mitk::RdfStore::Add ( RdfTriple triple )

Add a new triple to the triplestore. Checks if the triplestore contains the triple.

Parameters

triple A triple.

Returns: If the triple is successfully added or if the triplestore already contains the triple, true will be returned. If none of the previous options happen, false will be returned.

Definition at line 575 of file mitkRdfStore.cpp.

void mitk::RdfStore::AddPrefix	(	std::string	prefix,
		RdfUri	uri
	)

Add a new prefix which represents an URI as an abbreviation to the triplestore.

Parameters

prefix	The short form of an URI.
uri	The full form of an URI.

Definition at line 560 of file mitkRdfStore.cpp.

void mitk::RdfStore::CleanUp ( )

Clean up the triplestore to the state of a new store.

Definition at line 570 of file mitkRdfStore.cpp.

bool mitk::RdfStore::Contains ( RdfTriple triple )

Checks if the triplestore contains the triple.

Parameters

triple A triple.

Returns: If the triplestore contains the triple, true will be returned. Otherwise, false will be returned.

Definition at line 585 of file mitkRdfStore.cpp.

bool mitk::RdfStore::ExecuteBooleanQuery ( const std::string & query ) const

Tests whether or not the specified query pattern has a solution.

Parameters

query The SPARQL query string in ASK form.

Returns: True if query pattern has a solution, otherwise false.

Exceptions

mitk::Exception This exception is thrown if one of the following errors occur: (1) failure on query object creation, (2) SPARQL syntax error, (3) trying to execute a non-boolean query, (4) error while retrieving execution result

Definition at line 600 of file mitkRdfStore.cpp.

ResultMap mitk::RdfStore::ExecuteTupleQuery ( const std::string & query ) const

Queries over the triplestore with the given SPARQL query.

Parameters

query A std:string which stands for a SPARQL query text.

Returns: The result of the query will be returned as a map of keys with their values as lists of nodes.

Definition at line 595 of file mitkRdfStore.cpp.

RdfUri mitk::RdfStore::GetBaseUri ( ) const

Get the base URI of the triplestore.

Definition at line 555 of file mitkRdfStore.cpp.

PrefixMap mitk::RdfStore::GetPrefixes ( ) const

Get a Map with all prefixes of the triplestore.

Returns: A Map with all Prefixes of the RdfStore.

Definition at line 565 of file mitkRdfStore.cpp.

void mitk::RdfStore::Import	(	std::string	url,
		std::string	format = `""`
	)

Imports the state of the triplestore of an URL (URI).

Parameters

filename	A full filepath to the lokal storage or http address as URL. A lokal file path has to look like "file:YOURPATH" ( Example: file:D:/home/readme.txt ).
format	The current supported formats are: "turtle" (default), "ntriples", "nquads".

Definition at line 610 of file mitkRdfStore.cpp.

ResultMap mitk::RdfStore::Query ( const std::string & query ) const

Queries over the triplestore with the given SPARQL query.

Parameters

query A std:string which stands for a SPARQL query text.

Returns: The result of the query will be returned as a map of keys with their values as lists of nodes.

Deprecated:: (as of 2016_03) Use mitk::RdfStore::ExecuteTupleQuery() instead.

Definition at line 590 of file mitkRdfStore.cpp.

bool mitk::RdfStore::Remove ( RdfTriple triple )

Remove a triple from the triplestore. Checks if the triplestore contains the triple.

Parameters

triple A triple.

Returns: If the triple is successfully removed or if the triplestore doesn't contain the triple, true will be returned. If none of the previous options happen, false will be returned.

Definition at line 580 of file mitkRdfStore.cpp.

void mitk::RdfStore::Save	(	std::string	filename,
		std::string	format = `""`
	)

Saves the current state of the triplestore in a file. The currently supported formats are: "ntriples", "turtle"(default), "nquads".

Parameters

filename	A full filepath to the lokal storage.
format	One of the supported formats. Default: "turtle".

Definition at line 605 of file mitkRdfStore.cpp.

void mitk::RdfStore::SetBaseUri ( RdfUri uri )

Set the base URI of the triplestore.

Parameters

uri	An URI which is the base for the triplestore and for new nodes.
