Method Summary

Modifier and Type	Method	Description
boolean	run(@Nullable SocketConnection connection, @Nullable GObject sourceObject)	The ::run signal is emitted in a worker thread in response to an incoming connection.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, MemorySegment, MemorySegment) method.
default int	upcall(MemorySegment sourceThreadedSocketService, MemorySegment connection, MemorySegment sourceObject)	The upcall method is called from native code.

Method Details

run

boolean run(@Nullable SocketConnection connection,
 @Nullable GObject sourceObject)

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.

upcall

default int upcall(MemorySegment sourceThreadedSocketService,
 MemorySegment connection,
 MemorySegment sourceObject)

The upcall method is called from native code. The parameters are marshaled and run(SocketConnection, GObject) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(MemorySegment, MemorySegment, MemorySegment) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
