Interface IComponentFeature

public interface IComponentFeature

A component feature is a pluggable part of the state and behavior of a component. This interface represents the internal view of the instance level of a feature.

Method Summary

Modifier and Type	Method and Description
IFuture<java.lang.Void>	body() Execute the main activity of the feature.
IParameterGuesser	getParameterGuesser() The feature can add objects for field or method injections by providing an optional parameter guesser.
IValueFetcher	getValueFetcher() The feature can inject parameters for expression evaluation by providing an optional value fetcher.
boolean	hasUserBody() Check if the feature potentially executed user code in body.
IFuture<java.lang.Void>	init() Initialize the feature.
void	kill() Kill is only invoked, when shutdown does not return due to timeout.
IFuture<java.lang.Void>	shutdown() Shutdown the feature.

Method Detail

init

IFuture<java.lang.Void> init()

Initialize the feature.

body

IFuture<java.lang.Void> body()

Execute the main activity of the feature.

shutdown

IFuture<java.lang.Void> shutdown()

Shutdown the feature.

kill

void kill()

Kill is only invoked, when shutdown does not return due to timeout. The feature should do any kind of possible cleanup, but no asynchronous operations.

getValueFetcher

IValueFetcher getValueFetcher()

The feature can inject parameters for expression evaluation by providing an optional value fetcher. The fetch order is the reverse init order, i.e., later features can override values from earlier features.

getParameterGuesser

IParameterGuesser getParameterGuesser()

The feature can add objects for field or method injections by providing an optional parameter guesser. The selection order is the reverse init order, i.e., later features can override values from earlier features.

hasUserBody

boolean hasUserBody()

Check if the feature potentially executed user code in body. Allows blocking operations in user bodies by using separate steps for each feature. Non-user-body-features are directly executed for speed. If unsure just return true. ;-)
