Class LazyMap<KeyType,ValueType>

java.lang.Object
  extended by 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
