Method Details

run

void run(DebugCategory category,
 DebugLevel level,
 String file,
 String function,
 int line,
 GObject object,
 DebugMessage message)

Function prototype for a logging function that can be registered with gst_debug_add_log_function(). Use G_GNUC_NO_INSTRUMENT on that function.

upcall

default void upcall(MemorySegment category,
 int level,
 MemorySegment file,
 MemorySegment function,
 int line,
 MemorySegment object,
 MemorySegment message,
 MemorySegment userData)

The upcall method is called from native code. The parameters are marshaled and run(org.freedesktop.gstreamer.gst.DebugCategory, org.freedesktop.gstreamer.gst.DebugLevel, java.lang.String, java.lang.String, int, org.gnome.gobject.GObject, org.freedesktop.gstreamer.gst.DebugMessage) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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