Method Detail

isAutowireCandidate

public boolean isAutowireCandidate(BeanDefinitionHolder bdHolder,
                                   DependencyDescriptor descriptor)

Determine if the provided bean definition is an autowire candidate.

To be considered a candidate the bean's autowire-candidate attribute must not have been set to 'false'.

Specified by:

isAutowireCandidate in interface AutowireCandidateResolver

Parameters:

bdHolder - the bean definition including bean name and aliases

descriptor - the descriptor for the target method parameter or field

Returns:

whether the bean definition qualifies as autowire candidate

getSuggestedValue

public java.lang.Object getSuggestedValue(DependencyDescriptor descriptor)

Description copied from interface: AutowireCandidateResolver

Determine whether a default value is suggested for the given dependency.

Specified by:

getSuggestedValue in interface AutowireCandidateResolver

Parameters:

descriptor - the descriptor for the target method parameter or field

Returns:

the value suggested (typically an expression String), or null if none found

getLazyResolutionProxyIfNecessary

public java.lang.Object getLazyResolutionProxyIfNecessary(DependencyDescriptor descriptor,
                                                          java.lang.String beanName)

Description copied from interface: AutowireCandidateResolver

Build a proxy for lazy resolution of the actual dependency target, if demanded by the injection point.

Specified by:

getLazyResolutionProxyIfNecessary in interface AutowireCandidateResolver

Parameters:

descriptor - the descriptor for the target method parameter or field

beanName - the name of the bean that contains the injection point

Returns:

the lazy resolution proxy for the actual dependency target, or null if straight resolution is to be performed
