Examples of org.apache.felix.framework.Logger

org.apache.felix.framework.Logger

This class mimics the standard OSGi LogService interface. An instance of this class is used by the framework for all logging. By default this class logs messages to standard out. The log level can be set to control the amount of logging performed, where a higher number results in more logging. A log level of zero turns off logging completely.

The log levels match those specified in the OSGi Log Service (i.e., 1 = error, 2 = warning, 3 = information, and 4 = debug). The default value is 1.

This class also uses the System Bundle's context to track log services and will use the highest ranking log service, if present, as a back end instead of printing to standard out. The class uses reflection to invoking the log service's method to avoid a dependency on the log interface.
