Interface XsDataStreamManager

public interface XsDataStreamManager

The XsDataStreamManager is used to manage and create instances of XsDataInputStream and XsDataOutputStream objects. For the most part, data streams created by the XsDataStreamManager are allocated by WebSphere eXtreme Scale runtime components.

Since:

7.1.1

Method Summary

XsDataInputStream	createInputStream(byte[] bytes) Create a new XsDataInputStream using the bytes specified as the data backing.
XsDataOutputStream	createOutputStream() Create a new XsDataOutputStream.

Method Detail

createInputStream

XsDataInputStream createInputStream(byte[] bytes)
                                    throws IOException

Create a new XsDataInputStream using the bytes specified as the data backing. Do not change the data while the stream is using the data. The manager will not copy the data.

Parameters:

bytes - - The data used to back the XsDataInputStream.

Returns:

XsDataInputStream - the stream used to read the data

Throws:

IOException - - an unexpected IO error creating the stream

createOutputStream

XsDataOutputStream createOutputStream()
                                      throws IOException

Create a new XsDataOutputStream. The type of storage used for the XsDataOutputStream data backing is unspecified. Close the XsDataOutputStream when finished, thereby allowing any pooling of underlying data buffers to be reclaimed by the system.

Returns:

XsDataOutputStream - the data output stream

Throws:

IOException - - an unexpected IO error creating the stream
