Overview

JSArray wrapper that automatically manages lifetime and provides convenient access to indices and Array functions.

JSArray() [1/5]

JSArray

(

)

Create empty Array.

JSArray() [2/5]

JSArray

(

const std::initializer_list< JSValue > &

values

)

Create Array from list of JSValues.

JSArray() [3/5]

JSArray

(

JSObjectRef

array_obj

)

Create Array from existing JSObjectRef (JavaScriptCore C API)

JSArray() [4/5]

JSArray

(

const JSArray &

other

)

Copy constructor (shallow copy, will point to same instance)

JSArray() [5/5]

JSArray ( JSContextRef ctx, JSValueRef val )

Member Function Documentation

context()

JSContextRef context ( ) const

inline

Get the bound context for this JSArray (it is cached at creation).

indexOf()

int indexOf	(	const JSValue &	val,
		int	start = 0 ) const

Find the index (location) of a certain value, will return -1 if not found.

length()

unsigned length

(

)

Get number of elements in the Array.

operator JSObjectRef()

operator JSObjectRef ( ) const

inline

Get the underlying JSObjectRef (JavaScriptCore C API)

operator=()

JSArray & operator=

(

const JSArray &

other

)

Assignment (shallow assignment, will point to same instance)

operator[]()

JSPropertyValue operator[]

(

unsigned

idx

)

const

Get a property by array index (numbering starts at 0)

push()

void push

(

const JSValue &

val

)

Push an element to back of Array.

set_context()

void set_context ( JSContextRef context )

inline

Set the JSContext for this JSArray.

Note

JSArrays created from within a JSCallback have a temporary JSContext that is destroyed when the callback returns. You will need to "move" any JSArrays created within these callbacks to the View's main context (call set_context() with the main context) before using them outside the callback.
