Method Details

run

boolean run(ControlSource self,
 ClockTime timestamp,
 ClockTime interval,
 int nValues,
 MemorySegment values)

Function for returning an array of values starting at a given timestamp.

upcall

default int upcall(MemorySegment self,
 long timestamp,
 long interval,
 int nValues,
 MemorySegment values)

The upcall method is called from native code. The parameters are marshaled and run(org.freedesktop.gstreamer.gst.ControlSource, org.freedesktop.gstreamer.gst.ClockTime, org.freedesktop.gstreamer.gst.ClockTime, int, java.lang.foreign.MemorySegment) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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