Method Summary

Modifier and Type	Method	Description
void	run(boolean synced)	Signaled on clocks with ClockFlags.NEEDS_STARTUP_SYNC set once the clock is synchronized, or when it completely lost synchronization.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, int) method.
default void	upcall(MemorySegment sourceClock, int synced)	The upcall method is called from native code.

Method Details

run

void run(boolean synced)

Signaled on clocks with ClockFlags.NEEDS_STARTUP_SYNC set once the clock is synchronized, or when it completely lost synchronization. This signal will not be emitted on clocks without the flag.

This signal will be emitted from an arbitrary thread, most likely not the application's main thread.

Since:

1.6

upcall

default void upcall(MemorySegment sourceClock,
 int synced)

The upcall method is called from native code. The parameters are marshaled and run(boolean) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
