Detailed Description

Low-level socket functionality.

This class provides low-level socket functionality.

Most users will prefer "cooked" interfaces like those of KStreamSocket or KServerSocket.

Descended classes from this one provide some other kinds of socket functionality, like proxying or specific socket types.

Author: Thiago Macieira thiag[email protected][email protected][email protected]e.org

Deprecated:: Use KSocketFactory or KLocalSocket instead

Member Enumeration Documentation

◆ Capabilities

enum KNetwork::KSocketDevice::Capabilities

Capabilities for the socket implementation.

KSocketDevice-derived classes can implement certain capabilities that are not available in the default class. These capabilities are described by these flags. The default KSocketDevice class has none of these capabilities.

For the negative capabilities (inabilities, the CanNot* forms), when a capability is not present, the implementation will default to the original behaviour.

Enumerator
CanConnectString	Can connect to hostnames. If this flag is present, the string form of connect() can be used.
CanBindString	Can bind to hostnames. If this flag is present, the string form of bind() can be used
CanNotBind	Can not bind. If this flag is present, this implementation cannot bind
CanNotListen	Can not listen. If this flag is present, this implementation cannot listen
CanMulticast	Can send multicast as well as join/leave multicast groups.
CanNotUseDatagrams	Can not use datagrams. Note that this implies multicast capability not being available either.

Implements KNetwork::KPassiveSocketBase.

Definition at line 362 of file k3socketdevice.cpp.

◆ addNewImpl()

void KSocketDevice::addNewImpl	(	KSocketDeviceFactoryBase *	factory,
		int	capabilities
	)

static

Definition at line 417 of file k3socketdevice.cpp.

◆ capabilities()

int KSocketDevice::capabilities ( ) const

virtual

Returns the set of capabilities this socket class implements.

The set of capabilities is defined as an OR-ed mask of Capabilities bits.

The default implementation is guaranteed to always return 0. That is, derived implementations always return bits where they differ from the system standard sockets.

Definition at line 129 of file k3socketdevice.cpp.

◆ close()

void KSocketDevice::close ( )

overridevirtual

Closes the socket.

Reimplemented from QIODevice.

Use this function to close the socket this object is holding open.

Implements KNetwork::KPassiveSocketBase.

Definition at line 223 of file k3socketdevice.cpp.

◆ connect()

bool KSocketDevice::connect	(	const KResolverEntry &	address,
		OpenMode	mode = `ReadWrite`
	)

overridevirtual

Connect to a remote host.

Implements KNetwork::KActiveSocketBase.

Definition at line 328 of file k3socketdevice.cpp.

◆ create() [1/2]

bool KSocketDevice::create ( const KResolverEntry & address )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Creates a socket but don't connect or bind anywhere.

Definition at line 276 of file k3socketdevice.cpp.

◆ create() [2/2]

bool KSocketDevice::create	(	int	family,
		int	type,
		int	protocol
	)

virtual

Creates a socket but don't connect or bind anywhere.

This function is the equivalent of the system call socket(2).

Definition at line 251 of file k3socketdevice.cpp.

◆ createDefault() [1/2]

KSocketDevice * KSocketDevice::createDefault ( KSocketBase * parent )

static

Creates a new default KSocketDevice object given the parent object.

The capabilities flag indicates the desired capabilities the object being created should possess. Those capabilities are not guaranteed: if no factory can provide such an object, a default object will be created.

Parameters

parent the KSocketBase parent

Definition at line 889 of file k3socketdevice.cpp.

◆ createDefault() [2/2]

KSocketDevice * KSocketDevice::createDefault	(	KSocketBase *	parent,
		int	capabilities
	)

static

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.This will create an object only if the requested capabilities match.

Parameters

parent	the parent
capabilities	the requested capabilities

Definition at line 904 of file k3socketdevice.cpp.

◆ createNotifier()

QSocketNotifier * KSocketDevice::createNotifier ( QSocketNotifier::Type type ) const

protectedvirtual

Creates a socket notifier of the given type.

This function is called by readNotifier(), writeNotifier() and exceptionNotifier() when they need to create a socket notifier (i.e., the first call to those functions after the socket is open). After that call, those functions cache the socket notifier and will not need to call this function again.

Reimplement this function in your derived class if your socket type requires a different kind of QSocketNotifier. The return value should be deleteable with delete. (close() deletes them).

Parameters

type	the socket notifier type

Definition at line 826 of file k3socketdevice.cpp.

◆ disconnect()

bool KSocketDevice::disconnect ( )

overridevirtual

Disconnects this socket.

Implements KNetwork::KActiveSocketBase.

Definition at line 385 of file k3socketdevice.cpp.

◆ exceptionNotifier()

QSocketNotifier * KSocketDevice::exceptionNotifier ( ) const

Returns a socket notifier for exceptional events on this socket.

The is created only when requested.

This function might return NULL.

Definition at line 682 of file k3socketdevice.cpp.

◆ externalAddress()

KSocketAddress KSocketDevice::externalAddress ( ) const

overridevirtual

Returns this socket's externally visible local address.

If this socket has a local address visible externally different from the normal local address (as returned by localAddress()), then return it.

Certain implementations will use proxies and thus have externally visible addresses different from the local socket values. The default implementation returns the same value as localAddress().

Note: This function may return an empty KSocketAddress. In that case, the externally visible address could/can not be determined.

Implements KNetwork::KPassiveSocketBase.

Definition at line 637 of file k3socketdevice.cpp.

◆ flush()

bool KSocketDevice::flush ( )

virtual

This call is not supported on sockets.

Reimplemented from QIODevice.

Definition at line 246 of file k3socketdevice.cpp.

◆ listen()

bool KSocketDevice::listen ( int backlog = 5 )

overridevirtual

Puts this socket into listening mode.

Implements KNetwork::KPassiveSocketBase.

Definition at line 309 of file k3socketdevice.cpp.

◆ localAddress()

KSocketAddress KSocketDevice::localAddress ( ) const

overridevirtual

Returns this socket's local address.

Implements KNetwork::KActiveSocketBase.

Definition at line 555 of file k3socketdevice.cpp.

◆ peekData()

		qint64	maxlen,
		KSocketAddress *	from = `nullptr`
	)

overridevirtual

Implements KNetwork::KActiveSocketBase.

Definition at line 499 of file k3socketdevice.cpp.

◆ peerAddress()

KSocketAddress KSocketDevice::peerAddress ( ) const

overridevirtual

Returns this socket's peer address.

If this implementation does proxying of some sort, this is the real external address, not the proxy's address.

Implements KNetwork::KActiveSocketBase.

Definition at line 596 of file k3socketdevice.cpp.

◆ poll() [1/2]

bool KSocketDevice::poll	(	bool *	input,
		bool *	output,
		bool *	exception = `nullptr`,
		int	timeout = `-1`,
		bool *	timedout = `nullptr`
	)

virtual

Executes a poll in the socket, via select(2) or poll(2).

The events polled are returned in the parameters pointers. Set any of them to NULL to disable polling of that event.

On exit, input, output and exception will contain true if an event of that kind is waiting on the socket or false if not. If a timeout occurred, set timedout to true (all other parameters are necessarily set to false).

Parameters

input	if set, turns on polling for input events
output	if set, turns on polling for output events
exception	if set, turns on polling for exceptional events
timeout	the time in milliseconds to wait for an event; 0 for no wait and any negative value to wait forever
timedout	on exit, will contain true if the polling timed out

Returns: true if the poll call succeeded and false if an error occurred

Definition at line 701 of file k3socketdevice.cpp.

◆ poll() [2/2]

bool KSocketDevice::poll	(	int	timeout = `-1`,
		bool *	timedout = `nullptr`
	)

Shorter version to poll for any events in a socket.

This call polls for input, output and exceptional events in a socket but does not return their states. This is useful if you need to wait for any event, but don't need to know which; or for timeouts.

Parameters

timeout	the time in milliseconds to wait for an event; 0 for no wait and any negative value to wait forever
timedout	on exit, will contain true if the polling timed out

Returns: true if the poll call succeeded and false if an error occurred

Definition at line 820 of file k3socketdevice.cpp.

◆ readData()

qint64 KSocketDevice::readData	(	char *	data,
		qint64	maxlen,
		KSocketAddress *	from = `nullptr`
	)

overridevirtual

Reads data and the source address from this socket.

Implements KNetwork::KActiveSocketBase.

Definition at line 477 of file k3socketdevice.cpp.

◆ readNotifier()

QSocketNotifier * KSocketDevice::readNotifier ( ) const

Returns a socket notifier for input on this socket.

The notifier is created only when requested. Whether it is enabled or not depends on the implementation.

This function might return NULL.

Definition at line 644 of file k3socketdevice.cpp.
