getLazyResolutionProxyIfNecessary(DependencyDescriptor descriptor,

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

getSuggestedValue(DependencyDescriptor descriptor)
Determine whether a default value is suggested for the given dependency.
|
boolean |
hasQualifier(DependencyDescriptor descriptor)
Determine whether the given descriptor declares a qualifier beyond the type
(typically - but not necessarily - a specific kind of annotation).
|
boolean |
isAutowireCandidate(BeanDefinitionHolder bdHolder,
DependencyDescriptor descriptor)
Determine whether the given bean definition qualifies as an
autowire candidate for the given dependency.
|
boolean |
isRequired(DependencyDescriptor descriptor)
Determine whether the given descriptor is effectively required.
