Interface FaultToleranceConfig

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface FaultToleranceConfig

Encapsulates all properties extracted from FT annotations and the Config so that the processing can be declared independent of the actual resolution mechanism. A configuration is bound to a specific invocation context which is not an argument to each of the provided methods but passed to the implementation upon construction. For another invocation another configuration instance is bound.

Field Detail

ALTERNATIVE_ASYNCHRONOUS_ANNNOTATIONS_PROPERTY

static final String ALTERNATIVE_ASYNCHRONOUS_ANNNOTATIONS_PROPERTY

A payara specific feature that allows to specify a list of annotation classes that have a similar effect as Asynchronous.

NO_ALTERNATIVE_ANNOTATIONS

static final Class<? extends Annotation>[] NO_ALTERNATIVE_ANNOTATIONS

Method Detail

asAnnotated

static FaultToleranceConfig asAnnotated(Class<?> target,
                                        Method method)

Returns:

A FaultToleranceConfig that behaves as stated by the present FT annotations. Method annotations take precedence over the Class level annotations.

getAnnotation

<A extends Annotation> A getAnnotation(Class<A> annotationType)

Returns the value of the given annotation type for the invocation context was bound to upon construction.

Parameters:

annotationType - type to lookup

Returns:

the annotation of the given type if present or null otherwise

isNonFallbackEnabled

default boolean isNonFallbackEnabled()

Check global generic annotation switch.

Returns:

true if (in addition to Fallback, which is always enabled) the other FT annotations are as well (default). Mostly used to disable these which will not disable Fallback.

isEnabled

default boolean isEnabled(Class<? extends Annotation> annotationType)

Check global annotation specific annotation switch.

Parameters:

annotationType - the annotation type to check

Returns:

true if the given annotation type is globally enabled, false if it is globally disabled

isMetricsEnabled

default boolean isMetricsEnabled()

Check for global metrics switch.

Returns:

true if metrics are enabled, false otherwise.

isAnnotationPresent

default boolean isAnnotationPresent(Class<? extends Annotation> annotationType)
