    • run

      Iterator run(Pad pad, @Nullable GstObject parent)
      The signature of the internal pad link iterator function.
      Parameters:
      pad - The GstPad to query.
      parent - the parent of pad. If the GST_PAD_FLAG_NEED_PARENT flag is set, parent is guaranteed to be not-null and remain valid during the execution of this function.
      Returns:

      a new GstIterator that will iterate over all pads that are linked to the given pad on the inside of the parent element.

      the caller must call gst_iterator_free() after usage.

    • upcall

      default MemorySegment upcall(MemorySegment pad, MemorySegment parent)
      The upcall method is called from native code. The parameters are marshaled and run(Pad, GstObject) 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:
      the native function pointer
