◆ Iterate()

Maybe< void > v8::Array::Iterate	(	Local< Context >	context,
		IterationCallback	callback,
		void *	callback_data
	)

Calls {callback} for every element of this array, passing {callback_data} as its {data} parameter. This function will typically be faster than calling {Get()} repeatedly. As a consequence of being optimized for low overhead, the provided callback must adhere to the following restrictions:

It must not allocate any V8 objects and continue iterating; it may allocate (e.g. an error message/object) and then immediately terminate the iteration.
It must not modify the array being iterated.
It must not call back into V8 (unless it can guarantee that such a call does not violate the above restrictions, which is difficult).
The {Local<Value> element} must not "escape", i.e. must not be assigned to any other {Local}. Creating a {Global} from it, or updating a v8::TypecheckWitness with it, is safe. These restrictions may be lifted in the future if use cases arise that justify a slower but more robust implementation.

Returns {Nothing} on exception; use a {TryCatch} to catch and handle this exception. When the {callback} returns {kException}, iteration is terminated immediately, returning {Nothing}. By returning {kBreak}, the callback can request non-exceptional early termination of the iteration.

◆ Length()

uint32_t v8::Array::Length ( ) const

◆ New() [1/3]

static Local< Array > v8::Array::New	(	Isolate *	isolate,
		int	length = `0`
	)

static

Creates a JavaScript array with the given length. If the length is negative the returned array will have length 0.

◆ New() [2/3]

static Local< Array > v8::Array::New	(	Isolate *	isolate,
		Local< Value > *	elements,
		size_t	length
	)

static

Creates a JavaScript array out of a Local<Value> array in C++ with a known length.

◆ New() [3/3]

static MaybeLocal< Array > v8::Array::New	(	Local< Context >	context,
		size_t	length,
		std::function< MaybeLocal< v8::Value >()>	next_value_callback
	)

static

Creates a JavaScript array from a provided callback.

Parameters

context	The v8::Context to create the array in.
length	The length of the array to be created.
next_value_callback	The callback that is invoked to retrieve elements for the array. The embedder can signal that the array initialization should be aborted by throwing an exception and returning an empty MaybeLocal.

Returns: The v8::Array if all elements were constructed successfully and an empty MaybeLocal otherwise.
