LeaseSerializer (Amazon Kinesis Client Library for Java

java.lang.Object
- com.amazonaws.services.kinesis.leases.impl.LeaseSerializer

All Implemented Interfaces:

ILeaseSerializer<Lease>
```
public class LeaseSerializer
extends java.lang.Object
implements ILeaseSerializer<Lease>
```
An implementation of ILeaseSerializer for basic Lease objects. Can also instantiate subclasses of Lease so that LeaseSerializer can be decorated by other classes if you need to add fields to leases.
