@Generated("io.github.jwharm.JavaGI")
public class UnixOutputStream
extends OutputStream
implements FileDescriptorBased, PollableOutputStream

GUnixOutputStream implements OutputStream for writing to a UNIX file descriptor, including asynchronous operations. (If the file descriptor refers to a socket or pipe, this will use poll() to do asynchronous I/O. If it refers to a regular file, it will fall back to doing asynchronous I/O in another thread.)

Note that <gio/gunixoutputstream.h> belongs to the UNIX-specific GIO interfaces, thus you have to use the gio-unix-2.0.pc pkg-config file file or the GioUnix-2.0 GIR namespace when using it.

Constructor Details

UnixOutputStream

public UnixOutputStream(MemorySegment address)

Create a UnixOutputStream proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

UnixOutputStream

public UnixOutputStream(int fd,
 boolean closeFd)
                 throws UnsupportedPlatformException

Creates a new GUnixOutputStream for the given fd.

If closeFd, is true, the file descriptor will be closed when the output stream is destroyed.

Parameters:

fd - a UNIX file descriptor

closeFd - true to close the file descriptor when done

Throws:

UnsupportedPlatformException - when run on a platform other than linux or macos

Method Details

getType

public static Type getType()

Get the GType of the UnixOutputStream class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected UnixOutputStream asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class OutputStream

getCloseFd

public boolean getCloseFd()

Returns whether the file descriptor of this UnixOutputStream will be closed when the stream is closed.

Returns:

true if the file descriptor is closed when done

getFd

public int getFd()

Return the UNIX file descriptor that the stream writes to.

Specified by:

getFd in interface FileDescriptorBased

Returns:

The file descriptor of this UnixOutputStream

setCloseFd

public void setCloseFd(boolean closeFd)

Sets whether the file descriptor of this UnixOutputStream shall be closed when the stream is closed.

Parameters:

closeFd - true to close the file descriptor when done

builder

public static UnixOutputStream.Builder<? extends UnixOutputStream.Builder> builder()

A UnixOutputStream.Builder object constructs a UnixOutputStream with the specified properties. Use the various set...() methods to set properties, and finish construction with UnixOutputStream.Builder.build().
