- Class
  Description
  ApplicationDefaults
  Used to disambiguate which version of `SymbolProvider` is being referenced.
  AspectDecorator
  A decorator used to create an interceptor that delegates each method's invocation to an `MethodAdvice` for advice.
  AspectInterceptorBuilder<T>
  A builder may be obtained from the `AspectDecorator` and allows more controlled creation of the created interceptor; it allows different methods to be given different advice, and allows methods to be omitted (in which case the method invocation passes through without advice).
  Builtin
  Marks services provided by this module that may need to be unambiguously referenced.
  ChainBuilder
  A service which can assemble an implementation based on a command interface, and an ordered list of objects implementing that interface (the "commands").
  ClassNameLocator
  Scans the classpath for top-level classes within particular packages.
  ClasspathMatcher
  Used to determine which files will be included in the set of matches paths within a particular package.
  ClasspathScanner
  Used to scan a portion of the classpath for files that match a particular pattern, defined by a `ClasspathMatcher`.
  ClasspathURLConverter
  Used by `ClassNameLocator` to convert URLs from one protocol to another.
  DefaultImplementationBuilder
  Creates default implementations of a class.
  ExceptionAnalysis
  An analysis of an exception (including nested exceptions).
  ExceptionAnalyzer
  Analyzes an exception, providing an analysis.
  ExceptionInfo
  Contains information about an analyzed exception.
  ExceptionTracker
  Used by `LoggingDecorator` to track which exceptions have been logged during the current request (the ExceptionTracker is perthread).
  FactoryDefaults
  Used to disambiguate which version of `SymbolProvider` is being referenced.
  LazyAdvisor
  An advisor that identifies methods which can be evaluated lazily and advises them.
  LoggingAdvisor
  A service used in conjunction with a service advisor method to add logging advice to a service.
  LoggingDecorator
  Service that can create a logging interceptor that wraps around a service implementation (or interceptor).
  MasterObjectProvider
  A service that acts as a chain-of-command over a number of `ObjectProvider`, but allows for the case where no object may be provided.
  OperationAdvisor
  Used from a service advice method to identify methods with the `Operation` annotation, and add advice for those methods.
  ParallelExecutor
  A service that allows work to occur in parallel using a thread pool.
  PerthreadManager
  Manages per-thread data, and provides a way for listeners to know when such data should be cleaned up.
  PerThreadValue<T>
  Provides access to per-thread (and, by extension, per-request) data, managed by the `PerthreadManager`.
  PipelineBuilder
  Creates a pipeline from a service interface and an ordered list of filters.
  PropertyShadowBuilder
  Creates a "shadow" of a property of an object.
  RegistryShutdownHub
  Event hub for notifications when the IOC `Registry` shuts down.
  RegistryShutdownListener
  Deprecated.
  In Tapestry 5.3, to be removed in a later release.
  ServiceActivity
  Provided by the `ServiceActivityScoreboard` to track a single service's state and activity.
  ServiceActivityScoreboard
  Provides access to the runtime details about services in the `Registry`.
  ServiceConfigurationListener
  Interface that defines listeners to services getting their distributed configuration.
  ServiceConfigurationListenerHub
  Service that collects the `ServiceConfigurationListener`s.
  ServiceLifecycleSource
  Provides access to user defined lifecycles (beyond the two built-in lifecycles: "singleton" and "primitive").
  ServiceOverride
  Used to override built in services.
  Status
  Used in `ServiceActivity` to identify the state of the service in terms of its overall lifecycle.
  StrategyBuilder
  A service implementation builder that operates around a `StrategyRegistry`, implementing a version of the Gang of Four Strategy pattern.
  SymbolProvider
  A provider of values for symbols, used by the `SymbolSource` service.
  SymbolSource
  Used to manage symbols, configuration properties whose value is evaluated at runtime.
  ThreadCleanupListener
  Deprecated.
  Deprecated in 5.4, use `PerthreadManager.addThreadCleanupCallback(Runnable)` instead.
  ThreadLocale
  Stores the locale for the current thread.
  ThunkCreator
  A thunk is a delayed calculation.
  UpdateListener
  Interface for objects which can periodically check for updates.
  UpdateListenerHub
  Manages a set of `UpdateListener`s.
