Platform

public abstract class Platform

Platform abstraction layer required to allow fluent logger implementations to work on differing Java platforms (such as Android or GWT). The Platform class is responsible for providing any platform specific APIs, including the mechanism by which logging backends are created.

To enable an additional logging platform implementation, the class name should be added to the list of available platforms before the default platform (which must always be at the end). Platform implementation classes must subclass Platform and have a public, no-argument constructor. Platform instances are created on first-use of a fluent logger and platform implementors must take care to avoid cycles during initialization and re-entrant behaviour.
