Class BasicNonByteBufferOperations

java.lang.Object

alluxio.examples.BasicNonByteBufferOperations

All Implemented Interfaces:

Callable<Boolean>

public final class BasicNonByteBufferOperations
extends Object
implements Callable<Boolean>

Basic example of using the FileSystem for writing to and reading from files.

This class is different from BasicOperations in the way writes happen. Over there ByteBuffer is used directly, where as here byte data is done via input/output streams.

This example also let users play around with how to work with files a bit more. The AlluxioStorageType is something that can be set, as well as ability to delete file if exists.
