Method Details

run

void run(@Nullable String senderName,
 String signalName,
 @Nullable Variant parameters)

Emitted when a signal from the remote object and interface that proxy is for, has been received.

Since 2.72 this signal supports detailed connections. You can connect to the detailed signal g-signal::x in order to receive callbacks only when signal x is received from the remote object.

Since:

2.26

upcall

default void upcall(MemorySegment sourceDBusProxy,
 MemorySegment senderName,
 MemorySegment signalName,
 MemorySegment parameters)

The upcall method is called from native code. The parameters are marshaled and run(java.lang.String, java.lang.String, org.gnome.glib.Variant) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
