Method Detail

delegatingProductionComponentMonitorFactory

public static ProductionComponentMonitor.Factory delegatingProductionComponentMonitorFactory(Collection<? extends ProductionComponentMonitor.Factory> factories)

Returns a monitor factory that delegates to the given factories, and ensures that any method called on this object, even transitively, does not throw a RuntimeException or return null.

If the delegate monitors throw an Error, then that will escape this monitor implementation. Errors are treated as unrecoverable conditions, and may cause the entire component's execution to fail.

createMonitorForComponent

public static ProductionComponentMonitor createMonitorForComponent(javax.inject.Provider<?> componentProvider,
                                                                   javax.inject.Provider<Set<ProductionComponentMonitor.Factory>> monitorFactorySetProvider)

Creates a new monitor for the given component, from a set of monitor factories. This will not throw a RuntimeException or return null.

noOpProductionComponentMonitorProvider

public static javax.inject.Provider<ProductionComponentMonitor> noOpProductionComponentMonitorProvider()

Returns a provider of a no-op component monitor.
