Interface LogService

LogService

public interface LogService

This LogService provides an extra method for querying the service about the current log level. Log entries that are less severe than the current log level will be discarded by the log.

The log levels have the following hierarchy:

1. LOG_ERROR
2. LOG_WARNING
3. LOG_INFO
4. LOG_DEBUG

Method Detail

getLogLevel

int getLogLevel()

Get the current log level. The log will discard log entries with a level that is less severe than the current level. E.g., if the current log level is LogService.LOG_WARNING then the log will discard all log entries with level LogService.LOG_INFO and LogService.LOG_DEBUG. I.e. there is no need for a bundle to try to send such log entries to the log. The bundle may actually save a number of CPU-cycles by getting the log level and do nothing if the intended log entry is less severe than the current log level.

Returns:

the lowest severity level that is accepted into the log.
