| static const int | kInternalFieldCount = V8_ARRAY_BUFFER_INTERNAL_FIELD_COUNT |
An instance of the built-in ArrayBuffer constructor (ES6 draft 15.13.5). This API is experimental and may change significantly.
| size_t v8::ArrayBuffer::ByteLength | ( | ) | const |
Data length in bytes.
|
static |
| Contents v8::ArrayBuffer::Externalize | ( | ) |
Make this ArrayBuffer external. The pointer to underlying memory block and byte length are returned as |Contents| structure. After ArrayBuffer had been etxrenalized, it does no longer owns 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| that has been set via Isolate::CreateParams.
| Contents v8::ArrayBuffer::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|.
| bool v8::ArrayBuffer::IsExternal | ( | ) | const |
Returns true if ArrayBuffer is externalized, that is, does not own its memory block.
| bool v8::ArrayBuffer::IsNeuterable | ( | ) | const |
Returns true if this ArrayBuffer may be neutered.
| void v8::ArrayBuffer::Neuter | ( | ) |
Neuters this ArrayBuffer and all its views (typed arrays). Neutering sets the byte length of the buffer and all typed arrays to zero, preventing JavaScript from ever accessing underlying backing store. ArrayBuffer should have been externalized and must be neuterable.
|
static |
Create a new ArrayBuffer. Allocate |byte_length| bytes. Allocated memory will be owned by a created ArrayBuffer and will be deallocated when it is garbage-collected, unless the object is externalized.
|
static |
Create a new ArrayBuffer over an existing memory block. The created array buffer is by default immediately in externalized state. The memory block will not be reclaimed when a created ArrayBuffer is garbage-collected.
