LogService¶
-
enum class SeverityLevel : uint8_t¶
Values:
-
enumerator LOG_ERROR¶
Indicates the bundle or service may not be functional.
Action should be taken to correct this situation.
-
enumerator LOG_WARNING¶
Indicates a bundle or service is still functioning but may experience problems in the future because of the warning condition.
-
enumerator LOG_INFO¶
May be the result of any change in the bundle or service and does not indicate a problem.
-
enumerator LOG_DEBUG¶
Used for problem determination and may be irrelevant to anyone but the bundle developer.
-
enumerator LOG_ERROR¶
-
class LogService¶
- #include <cppmicroservices/logservice/LogService.hpp>
Provides methods for bundles to write messages to the log.
LogService methods are provided to log messages; optionally with a ServiceReference object or an exception. Bundles must log messages in the OSGi environment with a severity level according to the following hierarchy:
LOG_ERROR
LOG_WARNING
LOG_INFO
LOG_DEBUG
Remark
This class is thread safe.
Public Functions
-
virtual ~LogService() = default¶
-
virtual void Log(SeverityLevel level, std::string const &message) = 0¶
Logs a message.
- Parameters:
level – The severity of the message. This should be one of the defined log levels but may be any integer that is interpreted in a user defined way.
message – Human readable string describing the condition or empty string.
-
virtual void Log(SeverityLevel level, std::string const &message, const std::exception_ptr ex) = 0¶
Logs a message.
- Parameters:
level – The severity of the message. This should be one of the defined log levels but may be any integer that is interpreted in a user defined way.
message – Human readable string describing the condition or empty string.
ex – The exception that reflects the condition or nullptr.
-
virtual void Log(ServiceReferenceBase const &sr, SeverityLevel level, std::string const &message) = 0¶
Logs a message.
- Parameters:
sr – The ServiceReferenceBase object of the service that this message is associated with or an invalid object.
level – The severity of the message. This should be one of the defined log levels but may be any integer that is interpreted in a user defined way.
message – Human readable string describing the condition or empty string.
-
virtual void Log(ServiceReferenceBase const &sr, SeverityLevel level, std::string const &message, const std::exception_ptr ex) = 0¶
Logs a message with an exception associated and a ServiceReference object.
- Parameters:
sr – The ServiceReferenceBase object of the service that this message is associated with or an invalid object.
level – The severity of the message. This should be one of the defined log levels but may be any integer that is interpreted in a user defined way.
message – Human readable string describing the condition or empty string.
ex – The exception that reflects the condition or nullptr.
