Method Summary

Modifier and Type	Method	Description
boolean	run(LoadEvent loadEvent, String failingUri, @Nullable GError error)	Emitted when an error occurs during a load operation.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, int, MemorySegment, MemorySegment) method.
default int	upcall(MemorySegment sourceWebView, int loadEvent, MemorySegment failingUri, MemorySegment error)	The upcall method is called from native code.

Method Details

run

boolean run(LoadEvent loadEvent,
 String failingUri,
 @Nullable GError error)

Emitted when an error occurs during a load operation. If the error happened when starting to load data for a page loadEvent will be LoadEvent.STARTED. If it happened while loading a committed data source loadEvent will be LoadEvent.COMMITTED. Since a load error causes the load operation to finish, the signal WebKitWebView::load-changed will always be emitted with LoadEvent.FINISHED event right after this one.

By default, if the signal is not handled, a stock error page will be displayed. You need to handle the signal if you want to provide your own error page.

upcall

default int upcall(MemorySegment sourceWebView,
 int loadEvent,
 MemorySegment failingUri,
 MemorySegment error)

The upcall method is called from native code. The parameters are marshaled and run(LoadEvent, String, GError) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
