```
public interface IteratorState
```
Represents the state of a resumable iterator. Such an iterator can be executed asynchronously and continued after an interruption. Each iteration will result in a new request to the server (which is stateless). The entire state of the iterator is encoded in this object and and is used by the server to decide what to return for the next iteration call.
Each IteratorState instance is coupled to the Key-Value Table that it was created for and is tailored for the type of iteration that generates it (i.e., KeyValueTable.keyIterator(java.lang.String, int, io.pravega.client.tables.IteratorState) vs KeyValueTable.entryIterator(java.lang.String, int, io.pravega.client.tables.IteratorState)). As such, an IteratorState instance is non-transferable between different types of iterations or between different Key-Value Tables. It is OK to pass a IteratorState generated from a KeyValueTable instance to another KeyValueTable instance for the same Key-Value Table.

Modifier and Type	Method	Description
`static IteratorState`	`fromBytes(java.nio.ByteBuffer buffer)`	Creates a new `IteratorState` from the given `ByteBuffer`.
`boolean`	`isEmpty()`	Gets a value indicating whether this `IteratorState` instance is empty.
`java.nio.ByteBuffer`	`toBytes()`	Serializes this `IteratorState` to a `ByteBuffer`.
