Method Summary

Modifier and Type	Method	Description
void	run(Value resolve, Value reject)	A function passed to jscValueNewPromise called during initialization
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, MemorySegment, MemorySegment) method.
default void	upcall(MemorySegment resolve, MemorySegment reject, MemorySegment userData)	The upcall method is called from native code.

Method Details

run

void run(Value resolve,
 Value reject)

A function passed to jscValueNewPromise called during initialization

It is called like a JavaScript function, so exceptions raised will not be propagated to the context, but handled by the promise causing a rejection. resolve and reject can be reffed for later use to handle async task completion.

Parameters:

resolve - JSCValue function to call to resolve the promise

reject - JSCValue function to call to reject the promise

Since:

2.48

upcall

default void upcall(MemorySegment resolve,
 MemorySegment reject,
 MemorySegment userData)

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

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(MemorySegment, 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
