Public Functions

Type	Name
	PromiseWrapper (ObjectWrapper< managed > value) Wrap an existing JSValue. If managed is true, JSValue will be freed when the Promise is destroyed.
	PromiseWrapper (ContextRef ctx, JSValue val)

Type	Name
	ObjectWrapper (ValueWrapper< managed > value) Wrap an existing JSValue. If managed is true, JSValue will be freed when the Object is destroyed.
	ObjectWrapper (ContextRef ctx, JSValue val)
void	defineProperty (Id id, Value value, PropFlags flags=PropFlags::Default) Define a property of the object.
void	deleteProperty (Id id) Delete a property of the object.
T	get (Atom prop) Get a property of the object.
T	get (const std::string & name)
T	get (uint32_t idx)
std::vector< Atom >	getOwnPropertyNames (int flags=JS_GPN_STRING_MASK\|JS_GPN_ENUM_ONLY)
Object	getPrototype () Get the prototype of the object.
bool	hasProperty (Id id) Check if the object has a property.
Res	invoke (Atom key, Args... args) Invoke a method of the object.
Res	invoke (const std::string & key, Args... args)
Res	invoke (uint32_t idx, Args... args)
void	set (Atom prop, T val) Set a property of the object.
void	set (const std::string & name, T val)
void	set (uint32_t idx, T val)
void	setPrototype (Object proto) Set the prototype of the object.

Type	Name
	ValueWrapper (ContextRef ctx, JSValue val) Wrap an existing JSValue. If managed is true, JSValue will be freed when the Value is destroyed.
	ValueWrapper (const ValueWrapper & other)
	ValueWrapper (ValueWrapper && other)
JSValue &	getVal () Get reference to the underlying JSValue.
bool	isArray () Check if the Value is an array.
bool	isBigInt () Check if the Value is BigInt.
bool	isBoolean () Check if the Value is boolean.
bool	isFunction () Check if the Value is a function.
bool	isInstanceOf (ObjectWeak obj) Check if the Value is an instance of the given object.
bool	isNull () Check if the Value is null.
bool	isNumber () Check if the Value is number.
bool	isObject () Check if the Value is an object.
bool	isString () Check if the Value is string.
bool	isSymbol () Check if the Value is symbol.
bool	isUndefined () Check if the Value is undefined.
std::pair< ContextRef, JSValue >	loot () Release ownership of the JSValue. The JSValue will have to be freed manually.
	operator ValueWeak ()
ValueWrapper &	operator= (const ValueWrapper & other)
ValueWrapper &	operator= (ValueWrapper && other)
Value	stringify (int indent=0) Convert the Value to a JSON representation.
T	to () Convert the Value to a specified type.
StringView	toString () Convert the Value to a StringView .
	~ValueWrapper ()

Type	Name
std::tuple< Promise, Function, Function >	create (ContextRef ctx) Create a new Promise object.

Type	Name
Object	create (ContextRef ctx) Create a new empty object.

Type	Name
Value	from (ContextRef ctx, T val) Create a new Value by converting a given value.
Value	fromJSON (ContextRef ctx, std::string json, std::string filename="<json>", bool extended=false) Create a new Value from a given JSON string.
Value	null (ContextRef ctx) Create a new Value containing null.
Value	undefined (ContextRef ctx) Create a new Value containing undefined.

Type	Name
ContextRef	_ctx
JSValue	_val

Template parameters:

Wrap an existing JSValue. If managed is true, JSValue will be freed when the Promise is destroyed.

inline jac::PromiseWrapper::PromiseWrapper (
    ObjectWrapper < managed > value
)

Note:

Used internally when directly working with QuickJS API. New Promise should be created using Promise::create().

Parameters:

inline jac::PromiseWrapper::PromiseWrapper (
    ContextRef ctx,
    JSValue val
)

Create a new Promise object.

static inline std::tuple< Promise , Function , Function > jac::PromiseWrapper::create (
    ContextRef ctx
)

Returns:

Tuple of the Promise object, resolve function, reject function
