Examples of org.apache.commons.collections.KeyValue

org.apache.commons.collections.KeyValue
Defines a simple key value pair.
A Map Entry has considerable additional semantics over and above a simple key-value pair. This interface defines the minimum key value, with just the two get methods. @since Commons Collections 3.0 @version $Revision: 1.4 $ $Date: 2004/02/18 01:15:42 $ @author Stephen Colebourne
