Detailed Description

An instance of the built-in SharedArrayBuffer constructor. This API is experimental and may change significantly.

Member Function Documentation

◆ ByteLength()

size_t v8::SharedArrayBuffer::ByteLength ( ) const

Data length in bytes.

◆ Cast()

SharedArrayBuffer * v8::SharedArrayBuffer::Cast ( v8::Value value)
inlinestatic

◆ Externalize()

Contents v8::SharedArrayBuffer::Externalize ( )

Make this SharedArrayBuffer external. The pointer to underlying memory block and byte length are returned as |Contents| structure. After SharedArrayBuffer had been externalized, it does no longer own the memory block. The caller should take steps to free memory when it is no longer needed.

The memory block is guaranteed to be allocated with |Allocator::Allocate| by the allocator specified in v8::Isolate::CreateParams::array_buffer_allocator.

◆ GetContents()

Contents v8::SharedArrayBuffer::GetContents ( )

Get a pointer to the ArrayBuffer's underlying memory block without externalizing it. If the ArrayBuffer is not externalized, this pointer will become invalid as soon as the ArrayBuffer became garbage collected.

The embedder should make sure to hold a strong reference to the ArrayBuffer while accessing this pointer.

The memory block is guaranteed to be allocated with |Allocator::Allocate| by the allocator specified in v8::Isolate::CreateParams::array_buffer_allocator.

◆ IsExternal()

bool v8::SharedArrayBuffer::IsExternal ( ) const

Returns true if SharedArrayBuffer is externalized, that is, does not own its memory block.

◆ New() [1/2]

static Local< SharedArrayBuffer > v8::SharedArrayBuffer::New ( Isolate isolate,
size_t  byte_length 
)
static

Create a new SharedArrayBuffer. Allocate |byte_length| bytes. Allocated memory will be owned by a created SharedArrayBuffer and will be deallocated when it is garbage-collected, unless the object is externalized.

◆ New() [2/2]

static Local< SharedArrayBuffer > v8::SharedArrayBuffer::New ( Isolate isolate,
void *  data,
size_t  byte_length,
ArrayBufferCreationMode  mode = ArrayBufferCreationMode::kExternalized 
)
static

Create a new SharedArrayBuffer over an existing memory block. The created array buffer is immediately in externalized state unless otherwise specified. The memory block will not be reclaimed when a created SharedArrayBuffer is garbage-collected.
