Examples of org.picocontainer.defaults.CollectionComponentParameter

org.picocontainer.defaults.CollectionComponentParameter
A CollectionComponentParameter should be used to support inject an {@link Array}, a {@link Collection}or {@link Map}of components automatically. The collection will contain all components of a special type and additionally the type of the key may be specified. In case of a map, the map's keys are the one of the component adapter. @author Aslak Hellesøy @author Jörg Schaible @since 1.1
