Method Summary

Modifier and Type	Method	Description
boolean	run(IOChannel source, Set<IOCondition> condition, @Nullable MemorySegment data)	Specifies the type of function passed to g_io_add_watch() or g_io_add_watch_full(), which is called when the requested condition on a GIOChannel is satisfied.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, int, java.lang.foreign.MemorySegment) method.
default int	upcall(MemorySegment source, int condition, MemorySegment data)	The upcall method is called from native code.

Method Details

run

boolean run(IOChannel source,
 Set<IOCondition> condition,
 @Nullable
 @Nullable MemorySegment data)

Specifies the type of function passed to g_io_add_watch() or g_io_add_watch_full(), which is called when the requested condition on a GIOChannel is satisfied.

upcall

default int upcall(MemorySegment source,
 int condition,
 MemorySegment data)

The upcall method is called from native code. The parameters are marshaled and run(org.gnome.glib.IOChannel, java.util.Set<org.gnome.glib.IOCondition>, java.lang.foreign.MemorySegment) 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) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the function pointer will be allocated in this arena

Returns:

the native function pointer
