AsyncWorker

#include <bb/data/AsyncWorker>

To link against this class, add the following line to your .pro file: LIBS += -lbbdata

Represents objects that do asynchronous work.

You can extend this class and pass it to an AsyncDataAccess object and it will perform the work in another thread.

An AsyncWorker is expected to perform multiple operations with commands being passed to it using one of the execute functions in AsyncDataAccess.

See SqlWorker for a concrete example of how this can be used.

Inheritance

bb::data::AsyncWorker
	bb::data::SqlWorker

	AsyncWorker (QObject *parent=0)
virtual	~AsyncWorker ()
void	execute (const QVariant &criteria, bb::data::DataAccessReply *replyData)=0

Constructs a worker that will perform asynchronous work.

Ownership will be managed by the async framework. The object ownership will be transferred to an internal object within this framework.

Executes a task asynchronously in another thread provided by AsyncDataAccess.

This method will ultimately be called when either AsyncDataAccess::execute() or AsyncDataAccess::executeAndWait() is called.

Parameters
criteria	The work to be performed such as an SQL query command.
replyData	An output parameter, which is a pointer to an object that is updated with work results.
