Method Summary

Modifier and Type	Method	Description
boolean	run(DatagramBased datagramBased, Set<IOCondition> condition, @Nullable MemorySegment data)	This is the function type of the callback used for the GSource returned by g_datagram_based_create_source().
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, int, MemorySegment) method.
default int	upcall(MemorySegment datagramBased, int condition, MemorySegment data)	The upcall method is called from native code.

Method Details

run

boolean run(DatagramBased datagramBased,
 Set<IOCondition> condition,
 @Nullable MemorySegment data)

This is the function type of the callback used for the GSource returned by g_datagram_based_create_source().

Parameters:

datagramBased - the GDatagramBased

condition - the current condition at the source fired

data - data passed in by the user

Returns:

G_SOURCE_REMOVE if the source should be removed, G_SOURCE_CONTINUE otherwise

Since:

2.48

upcall

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

The upcall method is called from native code. The parameters are marshaled and run(DatagramBased, Set, MemorySegment) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
