Method Summary

Modifier and Type	Method	Description
void	run(SocketListenerEvent event, Socket socket)	Emitted when listener's activity on socket changes state.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, int, java.lang.foreign.MemorySegment) method.
default void	upcall(MemorySegment sourceSocketListener, int event, MemorySegment socket)	The upcall method is called from native code.

Method Details

run

void run(SocketListenerEvent event,
 Socket socket)

Emitted when listener's activity on socket changes state. Note that when listener is used to listen on both IPv4 and IPv6, a separate set of signals will be emitted for each, and the order they happen in is undefined.

upcall

default void upcall(MemorySegment sourceSocketListener,
 int event,
 MemorySegment socket)

The upcall method is called from native code. The parameters are marshaled and run(org.gnome.gio.SocketListenerEvent, org.gnome.gio.Socket) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, int, java.lang.foreign.MemorySegment) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the function pointer will be allocated in this arena

Returns:

the native function pointer
