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.

Member Function Documentation
const KSocketAddress & KReverseResolver::address | ( | ) | const |
Returns the socket address which was subject to resolution.
Definition at line 151 of file kreverseresolver.cpp.
Overrides event handling.
Reimplemented from QObject.
Definition at line 173 of file kreverseresolver.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 136 of file kreverseresolver.cpp.
void KNetwork::KReverseResolver::finished | ( | const KReverseResolver & | obj | ) | [signal] |
This signal is emitted when the resolution has finished.
- Parameters:
-
obj this class, which contains the results
bool KReverseResolver::isRunning | ( | ) | const |
This function returns 'true' if the processing is still running.
Definition at line 126 of file kreverseresolver.cpp.
QString KReverseResolver::node | ( | ) | const |
Returns the resolved node name, if the resolution has finished successfully, or QString::null otherwise.
Definition at line 141 of file kreverseresolver.cpp.
bool KReverseResolver::resolve | ( | const struct sockaddr * | sa, | |
Q_UINT16 | 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:
-
sa the sockaddr structure containing the address to be resolved salen the length of the sockaddr structure node the QString where we will store the resolved node serv the QString where we will store the resolved service flags flags to be used for this resolution.
- Returns:
- true if the resolution succeeded, false if not
- See also:
- ReverseFlags for the possible values for
flags

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:
-
addr the socket address to be resolved node the QString where we will store the resolved node serv the QString where we will store the resolved service flags flags to be used for this resolution.
- Returns:
- true if the resolution succeeded, false if not
- See also:
- ReverseFlags for the possible values for
flags

QString KReverseResolver::service | ( | ) | const |
Returns the resolved service name, if the resolution has finished successfully, or QString::null otherwise.
Definition at line 146 of file kreverseresolver.cpp.
bool KReverseResolver::start | ( | ) |
Starts the resolution.
This function returns 'true' if the resolution has started successfully.
Definition at line 156 of file kreverseresolver.cpp.
bool KReverseResolver::success | ( | ) | const |
This function returns true if the processing has finished with success, false if it's still running or failed.
