[Springframework-developer] AbstractFactoryBean implements PropertyValuesProviderFactoryBean, but comments say it doesn't

[Colin S. <col...@ex...>]

AbstractFactoryBean currently implements 
PropertyValuesProviderFactoryBean. However, comments within it say it 
doesn't. Anybody know how this discrepancy happened?

public abstract class AbstractFactoryBean implements 
PropertyValuesProviderFactoryBean {
  ...
    /**
     * Implementation of PropertyValuesProviderFactoryBean interface. 
Not declared on
     * this class, but subclass can choose to treat this interface as a 
tag interface.
     * Only used if the subclass implements 
PropertyValuesProviderFactoryBean (which
     * it can do without any additional code). This implementation will 
always return
     * the same properties for all objects, ignoring the bean name 
parameter.
     * @param name name of the bean we're creating
     * @see 
org.springframework.beans.factory.PropertyValuesProviderFactoryBean#getPropertyValues(String)
     */
    public PropertyValues getPropertyValues(String name) {
        return this.pvs;
    }
