public class VectorMap

extends AbstractMap

implements Cloneable

VectorMap is a debugging implementation of Map using a java.util.Vector of alternating keys and values, which is easier to browse in a debugger than a hash table. This is purposely flat, as debuggers can display the storage array as {key1, val1, key2, val2, ...}. The iterator is simple and quick; it may omit or repeat items if elements are removed or added during the iteration.
