The DBusModel provides a fully functional interface to a Model provided through a Soprano DBus server. It can thus, be seen as the counterpart to Server::DBusExportModel.
Given the DBus service name and the object path of the Model in question it handles all DBus communication transparently.
Normally there is no need to use this class directly as DBusClient does create instances of it on request.

Soprano::Client::DBusModel::~DBusModel | ( | ) |
void Soprano::Client::DBusModel::setAsyncCalls | ( | bool | b | ) |
Configure DBusModel to use asyncronous calls over DBus. With asyncronous calls DBusModel will enter local event loops while waiting for the reply. This way multiple calls can be performed interweaved. However, the application does not block, i.e. events (such as signals and slots) are handled which might not be wanted. If that is the case it is better to use Util::MutexModel instead.
b | If true asyncronous calls are enabled. |
bool Soprano::Client::DBusModel::asyncCalls | ( | ) | const |
true
if asyncronous calls are enabled. Error::ErrorCode Soprano::Client::DBusModel::addStatement | ( | const Statement & | statement | ) | [virtual] |
Add the Statement to the Model.
statement | The Statement to add. |
Implements Soprano::Model.
NodeIterator Soprano::Client::DBusModel::listContexts | ( | ) | const [virtual] |
List all contexts in the model, i.e. all named graphs.
Implements Soprano::Model.
QueryResultIterator Soprano::Client::DBusModel::executeQuery | ( | const QString & | query, | |
Query::QueryLanguage | language, | |||
const QString & | userQueryLanguage = QString() | |||
) | const [virtual] |
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.
StatementIterator Soprano::Client::DBusModel::listStatements | ( | const Statement & | partial | ) | const [virtual] |
Return an iterator over Model Statements that "partial" match the input Statement.
partial | The partial Statement to match. |
Implements Soprano::Model.
Error::ErrorCode Soprano::Client::DBusModel::removeStatement | ( | const Statement & | statement | ) | [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::Client::DBusModel::removeAllStatements | ( | const Statement & | statement | ) | [virtual] |
Default implementation is based on listStatements() and removeStatement().
Reimplemented from Soprano::StorageModel.
int Soprano::Client::DBusModel::statementCount | ( | ) | const [virtual] |
The number of statements stored in this Model.
Implements Soprano::Model.
bool Soprano::Client::DBusModel::isEmpty | ( | ) | const [virtual] |
Default implementation is based on Model::statementCount
Reimplemented from Soprano::StorageModel.
bool Soprano::Client::DBusModel::containsStatement | ( | const Statement & | statement | ) | const [virtual] |
Default implementation is based on Model::listStatements
Reimplemented from Soprano::StorageModel.
bool Soprano::Client::DBusModel::containsAnyStatement | ( | const Statement & | statement | ) | const [virtual] |
Default implementation is based on Model::listStatements
Reimplemented from Soprano::StorageModel.
Node Soprano::Client::DBusModel::createBlankNode | ( | ) | [virtual] |
Creates a new blank node with a unique identifier.
Implements Soprano::Model.
