Package com.google.common.flogger.backend.system

Class 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.context.ContextDataProvider.
    • flogger.clock: Provides an instance of com.google.common.flogger.backend.system.Clock.

    Note that if the com.google.flogger:flogger-grpc-context is also available and the value of the flogger.logging_context system property is "com.google.common.flogger.grpc.GrpcContextDataProvider#getInstance" then a gRPC based implementation of the ScopedLoggingContext API will be used.
