Package com.googlecode.objectify.impl

Class AsyncDatastoreReaderWriterImpl

java.lang.Object

com.googlecode.objectify.impl.AsyncDatastoreReaderWriterImpl

All Implemented Interfaces:

AsyncDatastoreReaderWriter

Direct Known Subclasses:

AsyncDatastoreImpl, AsyncTransactionImpl

public class AsyncDatastoreReaderWriterImpl
extends Object
implements AsyncDatastoreReaderWriter

The new datastore SDK has a neat structure of interfaces and implementations (transaction, datastorereader, etc) but doesn't currently support async operations. We need to shim in a Future-based API so that we can seamlessly support it when it becomes available. We'll remove this class then.
