Method Details

run

void run(@Nullable DBusObjectProxy objectProxy,
 @Nullable DBusProxy interfaceProxy,
 @Nullable Variant changedProperties,
 @Nullable String @Nullable [] invalidatedProperties)

Emitted when one or more D-Bus properties on proxy changes. The local cache has already been updated when this signal fires. Note that both changedProperties and invalidatedProperties are guaranteed to never be null (either may be empty though).

This signal exists purely as a convenience to avoid having to connect signals to all interface proxies managed by manager.

This signal is emitted in the thread-default main context (see MainContext.pushThreadDefault()) that manager was constructed in.

Since:

2.30

upcall

default void upcall(MemorySegment sourceDBusObjectManagerClient,
 MemorySegment objectProxy,
 MemorySegment interfaceProxy,
 MemorySegment changedProperties,
 MemorySegment invalidatedProperties)

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