Method Details

run

IteratorItem run(Iterator it,
 Value item)

The function that will be called after the next item of the iterator has been retrieved. This function can be used to skip items or stop the iterator.

 MemorySegment item)

The upcall method is called from native code. The parameters are marshaled and run(org.freedesktop.gstreamer.gst.Iterator, org.gnome.gobject.Value) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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