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.

Member Enumeration Documentation

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.

Member Function Documentation

KSocketDevice * KSocketDevice::accept ( )
overridevirtual

Accepts a new incoming connection.

Note: this function returns a socket of type KSocketDevice.

Implements KNetwork::KPassiveSocketBase.

Definition at line 364 of file k3socketdevice.cpp.

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

Adds a factory of KSocketDevice objects to the list, along with its capabilities flag.

Definition at line 934 of file k3socketdevice.cpp.

bool KSocketDevice::bind ( const KResolverEntry address)
overridevirtual

Binds this socket to the given address.

Implements KNetwork::KActiveSocketBase.

Definition at line 283 of file k3socketdevice.cpp.

qint64 KSocketDevice::bytesAvailable ( ) const
overridevirtual

Returns the number of bytes available for reading without blocking.

Reimplemented from QIODevice.

Definition at line 419 of file k3socketdevice.cpp.

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 131 of file k3socketdevice.cpp.

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 225 of file k3socketdevice.cpp.

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

Connect to a remote host.

Implements KNetwork::KActiveSocketBase.

Definition at line 330 of file k3socketdevice.cpp.

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 253 of file k3socketdevice.cpp.

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 278 of file k3socketdevice.cpp.

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
parentthe KSocketBase parent

Definition at line 891 of file k3socketdevice.cpp.

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
parentthe parent
capabilitiesthe requested capabilities

Definition at line 906 of file k3socketdevice.cpp.

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
typethe socket notifier type

Definition at line 828 of file k3socketdevice.cpp.

bool KSocketDevice::disconnect ( )
overridevirtual

Disconnects this socket.

Implements KNetwork::KActiveSocketBase.

Definition at line 387 of file k3socketdevice.cpp.

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 684 of file k3socketdevice.cpp.

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 639 of file k3socketdevice.cpp.

bool KSocketDevice::flush ( )
virtual

This call is not supported on sockets.

Reimplemented from QIODevice.

Definition at line 248 of file k3socketdevice.cpp.

bool KSocketDevice::listen ( int  backlog = 5)
overridevirtual

Puts this socket into listening mode.

Implements KNetwork::KPassiveSocketBase.

Definition at line 311 of file k3socketdevice.cpp.

KSocketAddress KSocketDevice::localAddress ( ) const
overridevirtual

Returns this socket's local address.

Implements KNetwork::KActiveSocketBase.

Definition at line 557 of file k3socketdevice.cpp.

qint64 KSocketDevice::peekData ( char *  data,
qint64  maxlen,
KSocketAddress from = nullptr 
)
overridevirtual

Peeks the data in the socket and the source address.

Implements KNetwork::KActiveSocketBase.

Definition at line 501 of file k3socketdevice.cpp.

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 598 of file k3socketdevice.cpp.

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
inputif set, turns on polling for input events
outputif set, turns on polling for output events
exceptionif set, turns on polling for exceptional events
timeoutthe time in milliseconds to wait for an event; 0 for no wait and any negative value to wait forever
timedouton exit, will contain true if the polling timed out
Returns

Definition at line 703 of file k3socketdevice.cpp.

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
timeoutthe time in milliseconds to wait for an event; 0 for no wait and any negative value to wait forever
timedouton exit, will contain true if the polling timed out
Returns
true if the poll call succeeded and false if an error occurred
