Detailed Description

A base class for an instance of one of "views" over ArrayBuffer, including TypedArrays and DataView (ES6 draft 15.13).

Definition at line 283 of file v8-array-buffer.h.

Member Function Documentation

◆ Buffer()

Local<ArrayBuffer> Buffer ( )

Returns underlying ArrayBuffer.

◆ ByteLength()

size_t ByteLength ( )

Size of a view in bytes.

◆ ByteOffset()

size_t ByteOffset ( )

Byte offset in |Buffer|.

◆ Cast()

static V8_INLINE ArrayBufferView* Cast ( Value *  value)
inlinestatic

Definition at line 315 of file v8-array-buffer.h.

◆ CopyContents()

size_t CopyContents ( void *  dest,
size_t  byte_length 
)

Copy the contents of the ArrayBufferView's buffer to an embedder defined memory without additional overhead that calling ArrayBufferView::Buffer might incur.

Will write at most min(|byte_length|, ByteLength) bytes starting at ByteOffset of the underlying buffer to the memory starting at |dest|. Returns the number of bytes actually written.

◆ HasBuffer()

bool HasBuffer ( ) const

Returns true if ArrayBufferView's backing ArrayBuffer has already been allocated.
