Class Hashtable.Enumerator

  +--java.util.Hashtable.Enumerator

private class Hashtable.Enumerator
extends Object
implements Enumeration, Iterator

A hashtable enumerator class. This class implements both the Enumeration and Iterator interfaces, but individual instances can be created with the Iterator methods disabled. This is necessary to avoid unintentionally increasing the capabilities granted a user by passing an Enumeration.

Field Summary
`(package private) Hashtable.Entry`	`entry`
`private int`	`expectedModCount` The modCount value that the iterator believes that the backing List should have.
`(package private) int`	`index`
`(package private) boolean`	`iterator` Indicates whether this Enumerator is serving as an Iterator or an Enumeration.
`(package private) Hashtable.Entry`	`lastReturned`
`(package private) Hashtable.Entry[]`	`table`
`(package private) int`	`type`

Constructor Summary
`(package private)`	`Hashtable.Enumerator(int type, boolean iterator)`

Method Summary
`boolean`	`hasMoreElements()`
`boolean`	`hasNext()`
`Object`	`next()`
`Object`	`nextElement()`
`void`	`remove()`

Field Detail

table

Hashtable.Entry[] table

index

int index

entry

Hashtable.Entry entry

lastReturned

Hashtable.Entry lastReturned

type

int type

iterator

boolean iterator

Indicates whether this Enumerator is serving as an Iterator or an Enumeration. (true -> Iterator).

expectedModCount

private int expectedModCount

The modCount value that the iterator believes that the backing List should have. If this expectation is violated, the iterator has detected concurrent modification.
