Model () |
A dummy model. All its methods do nothing and always fail with a default error.
A dummy model might be useful in situations where a null pointer could lead to crashes if creating a real model fails.
Definition at line 42 of file dummymodel.h.
Soprano::Util::DummyModel::DummyModel | ( | ) |
Create a new dummy model.
Soprano::Util::DummyModel::~DummyModel | ( | ) |
destructor
|
virtual |
Add the Statement to the Model.
statement | The Statement to add. |
Implements Soprano::Model.
Error::ErrorCode Soprano::Util::DummyModel::addStatement | ( | const Node & | subject, |
const Node & | predicate, | ||
const Node & | object, | ||
const Node & | context = Node() |
||
) |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
Reimplemented from Soprano::Model.
Error::ErrorCode Soprano::Util::DummyModel::addStatements | ( | const QList< Statement > & | statements | ) |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
Reimplemented from Soprano::Model.
|
virtual |
Remove one statement. For removing statements with wildward matching see removeAllStatements().
statement | The statement that should be removed. This has to be a valid statement. |
Implements Soprano::Model.
Error::ErrorCode Soprano::Util::DummyModel::removeStatement | ( | const Node & | subject, |
const Node & | predicate, | ||
const Node & | object, | ||
const Node & | context = Node() |
||
) |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
Reimplemented from Soprano::Model.
|
virtual |
Remove all statements that match the partial statement. For removing one specific statement see removeStatement().
statement | A possible partially defined statement that serves as a filter for all statements that should be removed. |
Implements Soprano::Model.
Error::ErrorCode Soprano::Util::DummyModel::removeStatements | ( | const QList< Statement > & | statements | ) |
Convenience method which removes all statements in statements.
Reimplemented from Soprano::Model.
Error::ErrorCode Soprano::Util::DummyModel::removeContext | ( | const Node & | ) |
Convenience method that removes all statements in the context.
Reimplemented from Soprano::Model.
Error::ErrorCode Soprano::Util::DummyModel::removeAllStatements | ( | ) |
Convenience method that clear the Model of all statements
Reimplemented from Soprano::Model.
|
virtual |
Return an iterator over Model Statements that "partial" match the input Statement.
partial | The partial Statement to match. |
Implements Soprano::Model.
StatementIterator Soprano::Util::DummyModel::listStatements | ( | const Node & | subject, |
const Node & | predicate, | ||
const Node & | object, | ||
const Node & | context = Node() |
||
) | const |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
subject | The subject node to match. Can be empty as a wildcard. |
predicate | The predicate node to match. Can be empty as a wildcard. |
object | The object node to match. Can be empty as a wildcard. |
context | The context node to match. Can be empty as a wildcard. |
Reimplemented from Soprano::Model.
StatementIterator Soprano::Util::DummyModel::listStatements | ( | ) | const |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
Reimplemented from Soprano::Model.
StatementIterator Soprano::Util::DummyModel::listStatementsInContext | ( | const Node & | context | ) | const |
Convenience method which lists all statements in context.
Reimplemented from Soprano::Model.
|
virtual |
List all contexts in the model, i.e. all named graphs.
Implements Soprano::Model.
|
virtual |
query_api_disabled Execute the given query over the Model.
This is a const read-only method. As such Model implementations should not support SPARQL extensions such as INSERT or UPDATE through this method. A future version of Soprano will provide an additional API for queries that change the Model.
query | The query to evaluate. |
language | The query language used to encode query . |
userQueryLanguage | If language equals Query::QueryLanguageUser userQueryLanguage defines the language to use. |
Implements Soprano::Model.
|
virtual |
Check if the model contains certain statements.
statement | A partially defined statement that serves as a pattern. |
Implements Soprano::Model.
bool Soprano::Util::DummyModel::containsAnyStatement | ( | const Node & | subject, |
const Node & | predicate, | ||
const Node & | object, | ||
const Node & | context = Node() |
||
) | const |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
subject | The subject node to match. Can be empty as a wildcard. |
predicate | The predicate node to match. Can be empty as a wildcard. |
object | The object node to match. Can be empty as a wildcard. |
context | The context node to match. Can be empty as a wildcard. |
Reimplemented from Soprano::Model.
|
virtual |
Check if the model contains a statements.
statement | The statement in question. This has to be a valid statement, i.e. subject, predicate, and object need to be defined. If the context node is empty the default graph is searched. |
Implements Soprano::Model.
