Class DefaultPlatform

java.lang.Object

com.google.common.flogger.backend.Platform

com.google.common.flogger.backend.system.DefaultPlatform

public class DefaultPlatform
extends com.google.common.flogger.backend.Platform

The default fluent logger platform for a server-side Java environment. The default platform implements the following behavior:

• It generates SimpleLoggerBackend logger backends.
• It uses a default clock implementation (only millisecond precision until Java 8).
• It does not provide support for injecting additional metadata into log statements.
• It determines call site information via stack analysis.

This class is designed to allow configuration via system properties. Each aspect of the platform is configured by providing the name of a static method, in the form "<package>.<class>#<method>", which returns an instance of the appropriate type. The namespace for system properties is:

• flogger.backend_factory: Provides an instance of com.google.common.flogger.backend.system.BackendFactory.
• flogger.logging_context: Provides an instance of com.google.common.flogger.backend.system.LoggingContext.
• flogger.clock: Provides an instance of com.google.common.flogger.backend.system.Clock.
