Method Summary

Modifier and Type	Method	Description
void	run(boolean remotePeerVanished, @Nullable GError error)	Emitted when the connection is closed.
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 sourceDBusConnection, int remotePeerVanished, MemorySegment error)	The upcall method is called from native code.

Method Details

run

void run(boolean remotePeerVanished,
 @Nullable
 @Nullable GError error)

Emitted when the connection is closed.

The cause of this event can be

• If g_dbus_connection_close() is called. In this case remotePeerVanished is set to false and error is null.

• If the remote peer closes the connection. In this case remotePeerVanished is set to true and error is set.

• If the remote peer sends invalid or malformed data. In this case remotePeerVanished is set to false and error is set.

Upon receiving this signal, you should give up your reference to connection. You are guaranteed that this signal is emitted only once.

upcall

default void upcall(MemorySegment sourceDBusConnection,
 int remotePeerVanished,
 MemorySegment error)

The upcall method is called from native code. The parameters are marshaled and run(boolean, org.gnome.glib.GError) 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
