Field Summary

Fields

Modifier and Type	Field	Description
static final BeanResolutionCustomizer	DEFAULT	The default customizer.

Method Summary

Modifier and Type	Method	Description
default boolean	isCandidateBean(Argument<?> beanType, QualifiedBeanType<?> candidate)	Returns whether the bean type is a candidate for the requested type.
default Argument<?>	resolveBeanLookupArgument(Argument<?> beanType)	Resolve an additional argument that may be used to find bean candidates if the requested type does not resolve a bean.
default <T> Optional<BeanDefinition<T>>	resolveNonUniqueBean(Argument<T> beanType, @Nullable Qualifier<T> qualifier, Collection<BeanDefinition<T>> candidates)	Resolve one bean from multiple qualified candidates before the default @Secondary, order, and default-implementation resolution rules are applied.
default Optional<?>	resolveNullBean(Argument<?> requestedBeanType, Argument<?> resolvedBeanType, BeanDefinition<?> beanDefinition)	Resolve a replacement value for a bean that was found but produced null.
default boolean	shouldDestroyDependentBeanAfterResolution(BeanResolutionContext resolutionContext, BeanDefinition<?> beanDefinition)	Returns whether a newly resolved dependent bean should be destroyed after the current bean resolution completes instead of being tracked as a dependent of the resolved bean.
default boolean	shouldInitializeBean(BeanResolutionContext resolutionContext, BeanDefinition<?> beanDefinition, Object bean)	Returns whether a newly constructed bean instance should receive field/method injection and initialization callbacks.
default boolean	shouldPreserveLazyProxyTargetResolutionPath(BeanResolutionContext resolutionContext, BeanDefinition<?> proxyBeanDefinition)	Returns whether a lazy proxy should preserve the current resolution path when storing the context that will later be used to resolve the proxy target.
default boolean	shouldResolveArrayAsBean(Argument<?> injectionPoint)	Whether an object array injection point should first resolve an exact array bean.

DEFAULT

static final BeanResolutionCustomizer DEFAULT

The default customizer.

Method Details

shouldResolveArrayAsBean

default boolean shouldResolveArrayAsBean(Argument<?> injectionPoint)

Whether an object array injection point should first resolve an exact array bean.

Parameters:

injectionPoint - The array injection point

Returns:

True to resolve an exact array bean

resolveBeanLookupArgument

default Argument<?> resolveBeanLookupArgument(Argument<?> beanType)

Resolve an additional argument that may be used to find bean candidates if the requested type does not resolve a bean.

Parameters:

beanType - The requested bean type

Returns:

The additional bean type to use for lookup

Since:

5.1.0

isCandidateBean

default boolean isCandidateBean(Argument<?> beanType,
 QualifiedBeanType<?> candidate)

Returns whether the bean type is a candidate for the requested type.

Parameters:

beanType - The requested bean type

candidate - The candidate bean type

Returns:

True if the candidate matches

Since:

5.1.0

resolveNonUniqueBean

default <T> Optional<BeanDefinition<T>> resolveNonUniqueBean(Argument<T> beanType,
 @Nullable Qualifier<T> qualifier,
 Collection<BeanDefinition<T>> candidates)

Resolve one bean from multiple qualified candidates before the default @Secondary, order, and default-implementation resolution rules are applied.

Type Parameters:

T - The bean type

Parameters:

beanType - The requested bean type

qualifier - The requested qualifier

candidates - The qualified candidates

Returns:

The resolved bean, or empty to use default resolution

Since:

5.1.0

resolveNullBean

default Optional<?> resolveNullBean(Argument<?> requestedBeanType,
 Argument<?> resolvedBeanType,
 BeanDefinition<?> beanDefinition)

Resolve a replacement value for a bean that was found but produced null.

Parameters:

requestedBeanType - The originally requested bean type

resolvedBeanType - The resolved bean lookup type

beanDefinition - The bean definition that produced null

Returns:

A replacement bean value, or empty to preserve the default behavior

Since:

5.1.0

shouldDestroyDependentBeanAfterResolution

default boolean shouldDestroyDependentBeanAfterResolution(BeanResolutionContext resolutionContext,
 BeanDefinition<?> beanDefinition)

Returns whether a newly resolved dependent bean should be destroyed after the current bean resolution completes instead of being tracked as a dependent of the resolved bean.

Parameters:

resolutionContext - The current resolution context

beanDefinition - The dependent bean definition

Returns:

True if the dependent bean should be destroyed after the current resolution completes

Since:

5.1.0

shouldInitializeBean

default boolean shouldInitializeBean(BeanResolutionContext resolutionContext,
 BeanDefinition<?> beanDefinition,
 Object bean)

Returns whether a newly constructed bean instance should receive field/method injection and initialization callbacks.

Parameters:

resolutionContext - The current resolution context

beanDefinition - The bean definition

bean - The newly constructed bean instance

Returns:

True if the bean instance should be injected and initialized

Since:

5.1.0

shouldPreserveLazyProxyTargetResolutionPath

default boolean shouldPreserveLazyProxyTargetResolutionPath(BeanResolutionContext resolutionContext,
 BeanDefinition<?> proxyBeanDefinition)

Returns whether a lazy proxy should preserve the current resolution path when storing the context that will later be used to resolve the proxy target.

Parameters:

resolutionContext - The current resolution context

proxyBeanDefinition - The proxy bean definition

Returns:

True if the current resolution path should be preserved

Since:

5.1.0
