Interface ReactorLogTarget

All Known Implementing Classes:

ReactorLogOsgiOptional, ReactorLogSystemOut

public interface ReactorLogTarget

Defines the API used by the Reaction package to submit log messages to a suitable log service. For example, standard POJO environments can use this interface to wrap java.util.logging and OSGi environments can use it to wrap org.osgi.service.log . Note that the log levels are intentionally chosen to match those used by the OSGi logging service.

Field Summary
