Detailed Description

Run a reverse-resolution on a socket address.

This class is provided as a counterpart to KResolver in such a way as it produces a reverse resolution: it resolves a socket address from its binary representations into a textual representation.

Most users will use the static functions resolve(), which work both synchronously (blocking) and asynchronously (non-blocking).

Member Enumeration Documentation

Flags for the reverse resolution.

These flags are used by the reverse resolution functions for setting resolution parameters. The possible values are:

  • NumericHost: don't try to resolve the host address to a text form. Instead, convert the address to its numeric textual representation.
  • NumericService: the same as NumericHost, but for the service name
  • NodeNameOnly: returns the node name only (i.e., not the Fully Qualified Domain Name)
  • Datagram: in case of ambiguity in the service name, prefer the name associated with the datagram protocol
  • NumericScope: for those addresses which have the concept of scope, resolve using the numeric value instead of the proper scope name.
  • ResolutionRequired: normally, when resolving, if the name resolution fails, the process normally converts the numeric address into its presentation forms. This flag causes the function to return with error instead.

Constructor & Destructor Documentation

KReverseResolver::KReverseResolver ( const KSocketAddress addr,
int  flags = 0,
QObject parent = nullptr 
)
explicit

Constructs this object to resolve the given socket address.

Parameters
addrthe address to resolve
flagsthe flags to use, see Flags
parentthe parent object (see QObject)

Definition at line 116 of file k3reverseresolver.cpp.

KReverseResolver::~KReverseResolver ( )
virtual

Destructor.

Definition at line 123 of file k3reverseresolver.cpp.

Member Function Documentation

const KSocketAddress & KReverseResolver::address ( ) const

Returns the socket address which was subject to resolution.

Definition at line 156 of file k3reverseresolver.cpp.

bool KReverseResolver::event ( QEvent e)
overridevirtual

Overrides event handling.

Reimplemented from QObject.

Definition at line 179 of file k3reverseresolver.cpp.

bool KReverseResolver::failure ( ) const

This function returns true if the processing has finished with failure, false if it's still running or succeeded.

Definition at line 141 of file k3reverseresolver.cpp.

void KNetwork::KReverseResolver::finished ( const KNetwork::KReverseResolver obj)
signal

This signal is emitted when the resolution has finished.

Parameters
objthis class, which contains the results
bool KReverseResolver::isRunning ( ) const

This function returns 'true' if the processing is still running.

Definition at line 131 of file k3reverseresolver.cpp.

QString KReverseResolver::node ( ) const

Returns the resolved node name, if the resolution has finished successfully, or QString() otherwise.

Definition at line 146 of file k3reverseresolver.cpp.

bool KReverseResolver::resolve ( const KSocketAddress addr,
QString node,
QString serv,
int  flags = 0 
)
static

Resolves a socket address to its textual representation.

FIXME!! How can we do this in a non-blocking manner!?

This function is used to resolve a socket address from its binary representation to a textual form, even if numeric only.

Parameters
addrthe socket address to be resolved
nodethe QString where we will store the resolved node
servthe QString where we will store the resolved service
flagsflags to be used for this resolution.
Returns
true if the resolution succeeded, false if not
See also
ReverseFlags for the possible values for flags

Definition at line 200 of file k3reverseresolver.cpp.

bool KReverseResolver::resolve ( const struct sockaddr *  sa,
quint16  salen,
QString node,
QString serv,
int  flags = 0 
)
static

Resolves a socket address to its textual representation.

FIXME!! How can we do this in a non-blocking manner!?

This function behaves just like the above one, except it takes a sockaddr structure and its size as parameters.

Parameters
sathe sockaddr structure containing the address to be resolved
salenthe length of the sockaddr structure
nodethe QString where we will store the resolved node
servthe QString where we will store the resolved service
flagsflags to be used for this resolution.
Returns
true if the resolution succeeded, false if not
See also
ReverseFlags for the possible values for flags

Definition at line 212 of file k3reverseresolver.cpp.

QString KReverseResolver::service ( ) const

Returns the resolved service name, if the resolution has finished successfully, or QString() otherwise.

Definition at line 151 of file k3reverseresolver.cpp.

bool KReverseResolver::start ( )

Starts the resolution.

This function returns 'true' if the resolution has started successfully.

Definition at line 161 of file k3reverseresolver.cpp.

bool KReverseResolver::success ( ) const

This function returns true if the processing has finished with success, false if it's still running or failed.

Definition at line 136 of file k3reverseresolver.cpp.
