Method Summary

Modifier and Type	Method	Description
boolean	run(Pad pad, @Nullable Event[] event)	Callback used by gst_pad_sticky_events_foreach().
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment) method.
default int	upcall(MemorySegment pad, MemorySegment event, MemorySegment userData)	The upcall method is called from native code.

Method Details

run

boolean run(Pad pad,
 @Nullable
 @Nullable Event[] event)

Callback used by gst_pad_sticky_events_foreach().

When this function returns true, the next event will be returned. When false is returned, gst_pad_sticky_events_foreach() will return.

When event is set to null, the item will be removed from the list of sticky events. event can be replaced by assigning a new reference to it. This function is responsible for unreffing the old event when removing or modifying.

upcall

default int upcall(MemorySegment pad,
 MemorySegment event,
 MemorySegment userData)

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

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the function pointer will be allocated in this arena

Returns:

the native function pointer
