org.ogf.saga.file

Class FileOutputStream

java.lang.Object

java.io.OutputStream

org.ogf.saga.file.FileOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable, Cloneable, SagaObject, Async

public abstract class FileOutputStream
extends OutputStream
implements SagaObject, Async

Since Java programmers are used to streams, the Java language bindings of SAGA provide them. In contrast to everything else in the language bindings, this is an abstract class, not an interface, because it is supposed to be a java.io.OutputStream (which is a class, not an interface). Implementations should redefine methods of java.io.OutputStream.

Modifier and Type	Method and Description
Object	clone() Clone is mentioned here because the inherited Object.clone() cannot hide the public version in SagaObject.clone().
abstract Task<FileOutputStream,Void>	close(TaskMode mode) Creates a task that closes this stream.
abstract Task<FileOutputStream,Void>	flush(TaskMode mode) Creates a task that flushes this stream.
Task<FileOutputStream,Void>	write(TaskMode mode, byte[] buf) Creates a task that writes a buffer to this stream.
abstract Task<FileOutputStream,Void>	write(TaskMode mode, byte[] buf, int off, int len) Creates a task that writes (part of) a buffer to this stream.
abstract Task<FileOutputStream,Void>	write(TaskMode mode, int b) Creates a task that writes a byte to this stream.

Method Detail

clone

public Object clone()
             throws CloneNotSupportedException

Clone is mentioned here because the inherited Object.clone() cannot hide the public version in SagaObject.clone().

Specified by:

clone in interface SagaObject

Overrides:

clone in class Object

Returns:

the clone.

Throws:

CloneNotSupportedException - when the clone method is not supported.

write

public abstract Task<FileOutputStream,Void> write(TaskMode mode,
                                int b)
                                           throws NotImplementedException

Creates a task that writes a byte to this stream. See OutputStream.write(int).

Parameters:

mode - the task mode.

Throws:

NotImplementedException - is thrown if the implementation does not provide an implementation of this method.

write

public abstract Task<FileOutputStream,Void> write(TaskMode mode,
                                byte[] buf,
                                int off,
                                int len)
                                           throws NotImplementedException

Creates a task that writes (part of) a buffer to this stream. See OutputStream.write(byte[], int, int).

Parameters:

mode - the task mode.

Throws:

NotImplementedException - is thrown if the implementation does not provide an implementation of this method.

write

public Task<FileOutputStream,Void> write(TaskMode mode,
                                byte[] buf)
                                  throws NotImplementedException

Creates a task that writes a buffer to this stream. See OutputStream.write(byte[]).

Parameters:

mode - the task mode.

Throws:

NotImplementedException - is thrown if the implementation does not provide an implementation of this method.

flush

public abstract Task<FileOutputStream,Void> flush(TaskMode mode)
                                           throws NotImplementedException

Creates a task that flushes this stream. See OutputStream.flush().

Parameters:

mode - the task mode.

Throws:

NotImplementedException - is thrown if the implementation does not provide an implementation of this method.

close

public abstract Task<FileOutputStream,Void> close(TaskMode mode)
                                           throws NotImplementedException

Creates a task that closes this stream. See OutputStream.close().

Parameters:

mode - the task mode.

Throws:

NotImplementedException - is thrown if the implementation does not provide an implementation of this method.
