Detailed Description
A simple logging system.
This class provides a simple but flexible approach to logging information that may be used for debugging or system operation diagnostics.
There is a single Logger for each application that uses QCA. You do not need to create this Logger yourself - QCA automatically creates it on startup. You can get access to the Logger using the global QCA::logger() method.
By default the Logger just accepts all messages (binary and text). If you want to get access to those messages, you need to subclass AbstractLogDevice, and register your subclass (using registerLogDevice()). You can then take whatever action is appropriate (e.g. show to the user using the GUI, log to a file or send to standard error).

Member Enumeration Documentation
◆ Severity
The severity of the message.
This information may be used by the log device to determine what the appropriate action is.

Member Function Documentation
◆ currentLogDevices()
QStringList QCA::Logger::currentLogDevices | ( | ) | const |
Get a list of the names of all registered log devices.
◆ level()
|
inline |
◆ logBinaryMessage()
void QCA::Logger::logBinaryMessage | ( | const QByteArray & | blob, |
Severity | = Information ) |
Log a binary blob to all available log devices.
- Parameters
-
blob the information to log
- Note
- how this is handled is quite logger specific. For example, it might be logged as a binary, or it might be encoded in some way
◆ logTextMessage()
void QCA::Logger::logTextMessage | ( | const QString & | message, |
Severity | = Information ) |
Log a message to all available log devices.
- Parameters
-
message the text to log
◆ registerLogDevice()
void QCA::Logger::registerLogDevice | ( | AbstractLogDevice * | logger | ) |
Add an AbstractLogDevice subclass to the existing list of loggers.
- Parameters
-
logger the LogDevice to add
◆ setLevel()
void QCA::Logger::setLevel | ( | Severity | level | ) |
Set the current logging level.
- Parameters
-
level new logging level
Only severities less or equal than the log level one will be logged
◆ unregisterLogDevice()
void QCA::Logger::unregisterLogDevice | ( | const QString & | loggerName | ) |
Remove an AbstractLogDevice subclass from the existing list of loggers.
- Parameters
-
loggerName the name of the LogDevice to remove
- Note
- If there are several log devices with the same name, all will be removed.
