static AsyncResult* Soprano::Util::AsyncResult::createResult

)

[static]

Constructor method to ensure binary compatibility.

Since:

2.2

Error::ErrorCode Soprano::Util::AsyncResult::errorCode

(

)

const

Convinience method which converts value() into a Error::ErrorCode as returned for the following AsyncModel methods:.

• AsyncModel::addStatementAsync
• AsyncModel::removeStatementAsync
• AsyncModel::removeAllStatementsAsync

See also:

value()

Since:

2.2

Node Soprano::Util::AsyncResult::node

(

)

const

Convinience method which converts value() into a StatementIterator as returned AsyncModel::createBlankNodeAsync.

See also:

value()

Since:

2.2

NodeIterator Soprano::Util::AsyncResult::nodeIterator

(

)

const

Convinience method which converts value() into a StatementIterator as returned AsyncModel::listContextsAsync.

See also:

value()

Since:

2.2

QueryResultIterator Soprano::Util::AsyncResult::queryResultIterator

(

)

const

Convinience method which converts value() into a StatementIterator as returned AsyncModel::executeQueryAsync.

value()

Since:

2.2

void Soprano::Util::AsyncResult::resultReady

(

Soprano::Util::AsyncResult *

)

[signal]

Emitted once the async operation is completed and the result can be read.

The result will delete itself.

void Soprano::Util::AsyncResult::setResult	(	const QVariant &	result,
		const Error::Error &	error
	)

Sets the final result and emits the resultReady signal.

This method should never be called by clients.

StatementIterator Soprano::Util::AsyncResult::statementIterator

(

)

const

Convinience method which converts value() into a StatementIterator as returned AsyncModel::listStatementsAsync.

See also:

value()

Since:

2.2

QVariant Soprano::Util::AsyncResult::value

(

)

const [inline]

The result of the async operation.

Its type is dependent on the operation (for example Error::ErrorCode for AsyncModel::addStatementAsync or StatementIterator for AsyncModel::listStatementsAsync). Types may need to be registered with Q_DECLARE_METATYPE.

Use Error::ErrorCache::lastError() to check for error details.

This value is not ready before resultReady() has been emitted. Do only use this in a slot connected to resultReady.
