Member Function Documentation

void DataSlave::dispatchNext (  )  [protected, slot]

dispatches next queued method.

Does nothing if there are no queued methods.

Definition at line 99 of file dataslave.cpp.

virtual void KIO::DataSlave::get ( const KUrl &  url  )  [pure virtual]

Implemented in KIO::DataProtocol.

void DataSlave::hold ( const KUrl &  url  )  [virtual]

Puts the kioslave associated with url at halt, and return it to klauncher, in order to let another application connect to it and finish the job.

This is for the krunner case: type a URL in krunner, it will start downloading to find the mimetype (KRun), and then hold the slave, publish the held slave using, this method, and the final application can continue the same download by requesting the same URL.

Reimplemented from KIO::Slave.

virtual void KIO::DataSlave::mimetype ( const KUrl &  url  )  [pure virtual]

Implemented in KIO::DataProtocol.

void DataSlave::resume (  )  [virtual]

Resumes the operation of the attached kioslave.

Reimplemented from KIO::Slave.

Definition at line 82 of file dataslave.cpp.

void DataSlave::send ( int  cmd,
const QByteArray &  arr = QByteArray() 
) [virtual]

Sends the given command to the kioslave.

Parameters:
cmd command id
arr byte array containing data

bool DataSlave::suspended (  )  [virtual]

Tells whether the kioslave is suspended.

Returns:
true if the kioslave is suspended.
