public class ThreadedSocketService
extends SocketService

A GThreadedSocketService is a simple subclass of SocketService that handles incoming connections by creating a worker thread and dispatching the connection to it by emitting the Gio.ThreadedSocketService::run signal in the new thread.

The signal handler may perform blocking I/O and need not return until the connection is closed.

The service is implemented using a thread pool, so there is a limited amount of threads available to serve incoming requests. The service automatically stops the SocketService from accepting new connections when all threads are busy.

As with SocketService, you may connect to Gio.ThreadedSocketService::run, or subclass and override the default handler.

Constructor Details

ThreadedSocketService

public ThreadedSocketService(MemorySegment address)

Create a ThreadedSocketService proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

ThreadedSocketService

public ThreadedSocketService(int maxThreads)

Creates a new GThreadedSocketService with no listeners. Listeners must be added with one of the GSocketListener "add" methods.

Parameters:

maxThreads - the maximal number of threads to execute concurrently handling incoming clients, -1 means no limit

Method Details

getType

public static Type getType()

Get the GType of the ThreadedSocketService class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected ThreadedSocketService 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 SocketService

run

protected boolean run(SocketConnection connection,
 GObject sourceObject)

onRun

public SignalConnection<ThreadedSocketService.RunCallback> onRun(ThreadedSocketService.RunCallback handler)

The ::run signal is emitted in a worker thread in response to an incoming connection. This thread is dedicated to handling connection and may perform blocking IO. The signal handler need not return until the connection is closed.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• ThreadedSocketService.RunCallback.run(org.gnome.gio.SocketConnection, org.gnome.gobject.GObject)

emitRun

public boolean emitRun(SocketConnection connection,
 @Nullable
 @Nullable GObject sourceObject)

Emits the "run" signal. See onRun(org.gnome.gio.ThreadedSocketService.RunCallback).

builder

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

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