Class LazyMap<KeyType,ValueType>

java.lang.Object
  org.opensaml.xml.util.LazyMap<KeyType,ValueType>

Type Parameters:

KeyType - the type of the map keys

ValueType - the type of the map values

All Implemented Interfaces:

java.io.Serializable, java.util.Map<KeyType,ValueType>

@NotThreadSafe
public class LazyMap<KeyType,ValueType>
extends java.lang.Object
implements java.util.Map<KeyType,ValueType>, java.io.Serializable

A map that is lazy initialized. This map takes very little memory when storing zero or one item.
