  org.springframework.beans.factory.support.ManagedMap

All Implemented Interfaces:

Map, BeanMetadataElement, Mergeable

public class ManagedMap
extends Object
implements Map, Mergeable, BeanMetadataElement

Tag collection class used to hold managed Map values, which may include runtime bean references (to be resolved into bean objects).

Wraps a target Map, which will be a linked map if possible (that is, if running on JDK 1.4 or if Commons Collections 3.x is available).
