Member Enumeration Documentation

enum QSparqlQueryOptions::ExecutionMethod

Execution method of the query.

Enumerator:

AsyncExec	Query is to be executed asynchronously. This is the default value of QSparqlQueryOptions.
SyncExec	Query is to be executed synchronously. See also: setExecutionMethod, executionMethod

enum QSparqlQueryOptions::Priority

Priority of the query.

Enumerator:

NormalPriority	Query is to be executed with normal priority. This is the default value of QSparqlQueryOptions.
LowPriority	Query is to be executed with low priority. Support for this option is driver-specfifc. See also: setPriority, priority

Constructor & Destructor Documentation

QSparqlQueryOptions::QSparqlQueryOptions

(

const QSparqlQueryOptions &

other

)

Creates a QSparqlQueryOptions object based on other, copying all option values from it.

Member Function Documentation

QSparqlQueryOptions::ExecutionMethod QSparqlQueryOptions::executionMethod

(

)

const

Returns the execution method of the query.

See also:

setExecutionMethod

bool QSparqlQueryOptions::isFireAndForget

(

)

const

Returns whether or not the query is to be executed in a "fire and forget" manner.

bool QSparqlQueryOptions::isForwardOnly

(

)

const

Returns whether or not an asynchronous query will be executed in a forward only manner.

QSparqlQueryOptions & QSparqlQueryOptions::operator=

(

const QSparqlQueryOptions &

other

)

Assigns the QSparqlQueryOptions object. Copies all option values from other.

QSparqlQueryOptions::Priority QSparqlQueryOptions::priority

(

)

const

Returns the priority of the query.

See also:

setPriority

void QSparqlQueryOptions::setExecutionMethod

(

ExecutionMethod

em

)

Sets the exeuction method of the query. The default execution method is QSparqlQueryOptions::AsyncExec.

See also:

executionMethod

void QSparqlQueryOptions::setFireAndForget

(

bool

fireAndForget

)

Sets whether or not to execute an QSparqlQuery::InsertStatment or QSparqlQuery::DeleteStatement in a "fire and forget" manner, where there is no requirement to wait on the result to finish. When using this option, no QSparqlResult::finished() signal will be emitted, and QSparqlResult::isFinished() will return true after the query is executed.

Support for this option is currently limited to the QTRACKER driver, and setting this for other statement types will have no effect.

void QSparqlQueryOptions::setForwardOnly

(

bool

forward

)

Sets whether or not to execute asynchronous queries in a ForwardOnly manner. Support for this option is currently limited to the QTRACKER_DIRECT driver.

See also:

QTRACKER_DIRECT specific usage

void QSparqlQueryOptions::setPriority

(

Priority

p

)

Sets the priority of the query. The default priority is QSparqlQueryOptions::NormalPriority.
