KeyIterator

All Known Implementing Classes:

KeyIteratorImpl
```
@Deprecated
public interface KeyIterator
```
Deprecated.
memcached 1.6.x will remove cachedump stats command,so this feature will be removed in the future

Key Iterator for memcached,use 'stats items' and 'stats cachedump' to iterate all keys,it is inefficient and not thread-safe.The 'stats cachedump" has length limitation,then iterator could not visit all keys if you have many keys.

Note: memcached 1.6.x will remove cachedump stats,so this feature will be invalid in memcached 1.6.x

All Methods Instance Methods Abstract Methods Deprecated Methods
Modifier and Type	Method	Description
`void`	`close()`	Deprecated. Close this iterator when you don't need it any more.It is not mandatory to call this method, but you might want to invoke this method for maximum performance.
`java.net.InetSocketAddress`	`getServerAddress()`	Deprecated. Get current iterator's memcached server address
`boolean`	`hasNext()`	Deprecated. Check if the iterator has more keys.
`java.lang.String`	`next()`	Deprecated. Get next key,if iterator has reached the end,throw ArrayIndexOutOfBoundsException
`void`	`setOpTimeout(long opTimeout)`	Deprecated. Set operation timeout,default is 1000 MILLISECONDS.
