org.apache.tools.ant.util.LazyHashtable<K,V>
All Implemented Interfaces:
Serializable, Cloneable, Map<K,V>
@Deprecated public class LazyHashtable<K,V> extends Hashtable<K,V>
Deprecated.
Hashtable implementation that allows delayed construction of expensive objects All operations that need access to the full list of objects will call initAll() first. Get and put are cheap.
