Detailed Description
\class FilterModel filtermodel.h Soprano/FilterModel
A FilterModel is a virtual model that wraps another Model.
FilterModels can be stacked to provide filtering on each of the Model's methods. A FilterModel has a parent model which is the data base for this filter. The parent can be an actual StorageModel or another FilterModel.
Error handling:
The FilterModel "inherits" its parent Model's errors, i.e. FilterModel.lastError() always equals FilterModel.parent()->lastError() (If the FilterModel implementations are called in subclasses).
Method Documentation
__init__ | ( | self ) |
Create an empty filter model.
__init__ | ( | self, | ||
Soprano.Model | parent | |||
) |
Create a new FilterModel which works on parent. Calls setParentModel.
- Parameters:
-
parent The parent Model.
Soprano.Error.ErrorCode addStatement | ( | self, | ||
Soprano.Statement | statement | |||
) |
Default implementation simply pipes the call through to the parent model.
Soprano.Error.ErrorCode addStatement | ( | self, | ||
Soprano.Node | subject, | |||
Soprano.Node | predicate, | |||
Soprano.Node | object, | |||
Soprano.Node | context=Soprano.Node() | |||
) |
Reimplemented for convenience. Calls Model.addStatement(const Node&,const Node&,const Node&,const Node&)
bool containsAnyStatement | ( | self, | ||
Soprano.Statement | statement | |||
) |
Default implementation simply pipes the call through to the parent model.
bool containsAnyStatement | ( | self, | ||
Soprano.Node | subject, | |||
Soprano.Node | predicate, | |||
Soprano.Node | object, | |||
Soprano.Node | context=Soprano.Node() | |||
) |
Reimplemented for convenience. Calls Model.containsAnyStatement(const Node&,const Node&,const Node&,const Node&)
bool containsStatement | ( | self, | ||
Soprano.Statement | statement | |||
) |
Default implementation simply pipes the call through to the parent model.
bool containsStatement | ( | self, | ||
Soprano.Node | subject, | |||
Soprano.Node | predicate, | |||
Soprano.Node | object, | |||

) |
Reimplemented for convenience. Calls Model.containsStatement(const Node&,const Node&,const Node&,const Node&)
Soprano.Node createBlankNode | ( | self ) |
Default implementation simply pipes the call through to the parent model.
Soprano.QueryResultIterator executeQuery | ( | self, | ||
QString | query, | |||
Soprano.Query.QueryLanguage | language, | |||
QString | userQueryLanguage=QString() | |||
) |
Default implementation simply pipes the call through to the parent model.
bool isEmpty | ( | self ) |
Default implementation simply pipes the call through to the parent model.
Soprano.NodeIterator listContexts | ( | self ) |
Default implementation simply pipes the call through to the parent model.
Soprano.StatementIterator listStatements | ( | self, | ||
Soprano.Statement | partial | |||
) |
Default implementation simply pipes the call through to the parent model.

Soprano.Node | subject, | |||
Soprano.Node | predicate, | |||
Soprano.Node | object, | |||
Soprano.Node | context=Soprano.Node() | |||
) |
Reimplemented for convenience. Calls Model.listStatements(const Node&,const Node&,const Node&,const Node&)
Soprano.Model parentModel | ( | self ) |
Get the parent model.
- Returns:
- The parent Model or 0 if none has been set.
parentStatementAdded | ( | self, | ||
Soprano.Statement | a0 | |||
) |
Handle a statementsAdded() signal from the parent Model.
The default implementation simply re-emits the signal.
parentStatementRemoved | ( | self, | ||
Soprano.Statement | a0 | |||
) |
Handle a statementsRemoved() signal from the parent Model.
The default implementation simply re-emits the signal.
parentStatementsAdded | ( | self ) |
Handle a statementsAdded() signal from the parent Model.
The default implementation simply re-emits the signal.
parentStatementsRemoved | ( | self ) |
Handle a statementsRemoved() signal from the parent Model.
The default implementation simply re-emits the signal.
Soprano.Error.ErrorCode removeAllStatements | ( | self, | ||
Soprano.Statement | statement | |||
) |
Default implementation simply pipes the call through to the parent model.

Soprano.Node | subject, | |||
Soprano.Node | predicate, | |||
Soprano.Node | object, | |||
Soprano.Node | context=Soprano.Node() | |||
) |

) |
Reimplemented for convenience. Calls Model.removeStatement(const Node&,const Node&,const Node&,const Node&)
setParentModel | ( | self, | ||
Soprano.Model | model | |||
) |
Set the parent Model.
- Parameters:
-
model The Model that this filter will forward any commands to.

Default implementation simply pipes the call through to the parent model.
Soprano.Error.ErrorCode write | ( | self, | ||
QTextStream | os | |||
) |
