Detailed Description

This class provides a high performance implementation for the data url scheme (rfc2397).

Do not use this class in external applications. It is an implementation detail of KIO and subject to change without notice.

Member Function Documentation

void DataSlave::dispatchNext

(

)

[protected, slot]

dispatches next queued method.

Does nothing if there are no queued methods.

Definition at line 101 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.

Definition at line 73 of file dataslave.cpp.

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 83 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

void DataSlave::sendMetaData

(

)

[protected]

Sends metadata set with setAllMetaData.

Definition at line 170 of file dataslave.cpp.

void DataSlave::setAllMetaData

(

const MetaData &

md

)

[protected]

Sets metadata.

Definition at line 166 of file dataslave.cpp.

void DataSlave::setConfig

(

const MetaData &

config

)

[virtual]

Configure slave.

Reimplemented from KIO::Slave.

Definition at line 156 of file dataslave.cpp.

void DataSlave::setHost	(	const QString &	host,
		quint16	port,
		const QString &	user,
		const QString &	passwd
	)		[virtual]

Set host for url.

Parameters:

host	to connect to.
port	to connect to.
user	to login as
passwd	to login with

Reimplemented from KIO::Slave.

void DataSlave::suspend

(

)

[virtual]

Suspends the operation of the attached kioslave.

Reimplemented from KIO::Slave.

Definition at line 77 of file dataslave.cpp.

bool DataSlave::suspended

(

)

[virtual]

Tells whether the kioslave is suspended.

Returns:

true if the kioslave is suspended.
