Method Summary

Modifier and Type	Method	Description
void	run(@Nullable Pad newPad)	a new GstPad has been added to the element.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment) method.
default void	upcall(MemorySegment sourceElement, MemorySegment newPad)	The upcall method is called from native code.

Method Details

run

void run(@Nullable Pad newPad)

a new GstPad has been added to the element. Note that this signal will usually be emitted from the context of the streaming thread. Also keep in mind that if you add new elements to the pipeline in the signal handler you will need to set them to the desired target state with gst_element_set_state() or gst_element_sync_state_with_parent().

upcall

default void upcall(MemorySegment sourceElement,
 MemorySegment newPad)

The upcall method is called from native code. The parameters are marshaled and run(org.freedesktop.gstreamer.gst.Pad) 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.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
