cloneIfNecessary back to summary

cloneIfNecessary	back to summary
public default AutowireCandidateResolver cloneIfNecessary() Return a clone of this resolver instance if necessary, retaining its local configuration and allowing for the cloned instance to get associated with a new bean factory, or this original instance if there is no such state. The default implementation creates a separate instance via the default class constructor, assuming no specific configuration state to copy. Subclasses may override this with custom configuration state handling or with standard `Cloneable` support (as implemented by Spring's own configurable `AutowireCandidateResolver` variants), or simply return `this` (as in `SimpleAutowireCandidateResolver`). Since 5.2.7 See Also `GenericTypeAwareAutowireCandidateResolver#cloneIfNecessary()`, `DefaultListableBeanFactory#copyConfigurationFrom`

hasQualifier back to summary

hasQualifier	back to summary
public default boolean hasQualifier(DependencyDescriptor descriptor) Determine whether the given descriptor declares a qualifier beyond the type (typically - but not necessarily - a specific kind of annotation). The default implementation returns `false`. Parameters descriptor:DependencyDescriptor the descriptor for the target method parameter or field Returns:boolean whether the descriptor declares a qualifier, narrowing the candidate status beyond the type match Since 5.1 See Also `org.springframework.beans.factory.annotation.QualifierAnnotationAutowireCandidateResolver#hasQualifier`

The default implementation returns false.

Parameters

descriptor:DependencyDescriptor: the descriptor for the target method parameter or field

Returns:boolean

whether the descriptor declares a qualifier, narrowing the candidate status beyond the type match
