org.apache.wicket.util.value.LongValue
All Implemented Interfaces:
Serializable, Comparable<LongValue>
Direct Known Subclasses:
Bytes
public class LongValue extends Object implements Comparable<LongValue>, Serializable
A base class based on the Java long primitive for value classes that want to implement standard operations on that value without the pain of aggregating a Long object.
