  • Method Details

    • run

      boolean run(@Nullable DBusMethodInvocation invocation)

      Emitted when a D-Bus peer is trying to change the debug settings and used to determine if that is authorized.

      This signal is emitted in a dedicated worker thread, so handlers are allowed to perform blocking I/O. This means that, for example, it is appropriate to call polkit_authority_check_authorization_sync() to check authorization using polkit.

      If false is returned then no further handlers are run and the request to change the debug settings is rejected.

      Otherwise, if true is returned, signal emission continues. If no handlers return false, then the debug settings are allowed to be changed.

      Signal handlers must not modify invocation, or cause it to return a value.

      The default class handler just returns true.

    • upcall

      default int upcall(MemorySegment sourceDebugControllerDBus, MemorySegment invocation)
      The upcall method is called from native code. The parameters are marshaled and run(DBusMethodInvocation) is executed.

    • toCallback

      default MemorySegment toCallback(Arena arena)
      Creates a native function pointer to the upcall(MemorySegment, MemorySegment) method.
      Specified by:
      toCallback in interface FunctionPointer
      Parameters:
      arena - the arena in which the function pointer is allocated
      Returns:
