Package-level declarations

Flogger is a fluent API for writing log messages.

This package is a part of the open-source Flogger library.

Types

AbstractLogger

public abstract class AbstractLogger<API extends LoggingApi<API>>

Base class for the fluent logger API.

FluentLogger2

public final class FluentLogger2 extends AbstractLogger<API>

The default implementation of AbstractLogger which returns the basic LoggingApi and uses the default parser and system configured backend.

LazyArg

public interface LazyArg<T>

Functional interface for allowing lazily evaluated arguments to be supplied to Flogger.

LazyArgs

public final class LazyArgs

Static utility methods for lazy argument evaluation in Flogger.

LogContext

public abstract class LogContext<LOGGER extends AbstractLogger<API>, API extends LoggingApi<API>> implements LoggingApi<API>, LogData

The base context for a logging statement, which implements the base logging API.

LoggingApi

public interface LoggingApi<API extends LoggingApi<API>>

The basic logging API.

LoggingScope

public abstract class LoggingScope

An opaque scope marker which can be attached to log sites to provide "per scope" behaviour for stateful logging operations (e.g.

LoggingScopeProvider

public interface LoggingScopeProvider

Provides a scope to a log statement via the per method.

LogPerBucketingStrategy

public abstract class LogPerBucketingStrategy<T>

Provides a strategy for "bucketing" a potentially unbounded set of log aggregation keys used by the <> method.

LogSite

public abstract class LogSite implements LogSiteKey

A value type which representing the location of a single log statement.

LogSiteKey

public interface LogSiteKey

A tagging interface to mark implementations that are suitable for use as a key for looking up per log site persistent state.

LogSiteMap

public abstract class LogSiteMap<V>

Provides per log site state for stateful fluent logging operations (e.g.

LogSites

public final class LogSites

Helper class to generate log sites for the current line of code.

LogSiteStackTrace

public final class LogSiteStackTrace extends Exception

A synthetic exception which can be attached to log statements when additional stack trace information is required in log files or via tools such as ECatcher.

MetadataKey

public class MetadataKey<T>

Key for logging semi-structured metadata values.

MetadataKeysKt

public final class MetadataKeysKt

RateLimitStatus

public abstract class RateLimitStatus

Status for rate limiting operations, usable by rate limiters and available to subclasses of LogContext to handle rate limiting consistently.

StackSize

public enum StackSize

Enum values to be passed into withStackTrace to control the maximum number of stack trace elements created.
