Creates a new logging.ComponentLoggerManager for application components and updates the framework's ComponentLoggerManager (which was bootstraped with a command-line supplied global log level) with the application's logging configuration.

func (*ApplicationLoggingFacilityBuilder) BuildAndRegister

func (alfb *ApplicationLoggingFacilityBuilder) BuildAndRegister(lm *logging.ComponentLoggerManager, ca *config.ConfigAccessor, cn *ioc.ComponentContainer) error

See FacilityBuilder.BuildAndRegister

func (*ApplicationLoggingFacilityBuilder) DependsOnFacilities

func (alfb *ApplicationLoggingFacilityBuilder) DependsOnFacilities() []string

See FacilityBuilder.DependsOnFacilities

func (*ApplicationLoggingFacilityBuilder) FacilityName

func (alfb *ApplicationLoggingFacilityBuilder) FacilityName() string

See FacilityBuilder.FacilityName

type FrameworkLogDecorator

type FrameworkLogDecorator struct {
	// The framework ComponentLoggerManager (as opposed to the application ComponentLoggerManager)
	LoggerManager *logging.ComponentLoggerManager

	// Logger to allow this decorator to log messages.
	FrameworkLogger logging.Logger
}

Injects a framework logger into Granitic framework components.

func (*FrameworkLogDecorator) DecorateComponent

func (fld *FrameworkLogDecorator) DecorateComponent(component *ioc.Component, container *ioc.ComponentContainer)

DecorateComponent injects a newly created Logger into the FrameworkLogger field of the subject component.

func (*FrameworkLogDecorator) OfInterest

func (fld *FrameworkLogDecorator) OfInterest(component *ioc.Component) bool

OfInterest returns true if the subject component has a field of type logging.Logger and the name FrameworkLogger.
