IFSFileOutputStream (JTOpen 20.0.7 API)

java.lang.Object
- java.io.OutputStream
- - com.ibm.as400.access.IFSFileOutputStream

All Implemented Interfaces:

Closeable, Flushable, Serializable, AutoCloseable

Direct Known Subclasses:

IFSTextFileOutputStream
```
public class IFSFileOutputStream
extends OutputStream
implements Serializable
```
Represents an integrated file system file output stream. An integrated file system file output stream is an output stream for writing data to integrated file system objects.
IFSFileOutputStream objects are capable of generating file events that call the following FileListener methods: fileClosed, fileModified, and fileOpended.
The following example illustrates the use of IFSFileOutputStream:
```
 // Work with /Dir/File on the system eniac.
 AS400 as400 = new AS400("eniac");
 IFSFileOutputStream file = new IFSFileOutputStream(as400, "/Dir/File");

 // Lock the first 8 bytes of the file.
 IFSKey key = file.lock(8);

 // Write 8 bytes to the file.
 byte[] data = { 0, 1, 2, 3, 4, 5, 6, 7 };
 file.write(data, 0, 8);

 // Unlock the first 8 bytes.
 file.unlock(key);

 // Close the file.
 file.close();
 
```
