Detailed Description

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

Member Function Documentation

◆ Buffer()

Local<ArrayBuffer> v8::ArrayBufferView::Buffer ( )

Returns underlying ArrayBuffer.

◆ ByteLength()

size_t v8::ArrayBufferView::ByteLength ( )

Size of a view in bytes.

◆ ByteOffset()

size_t v8::ArrayBufferView::ByteOffset ( )

Byte offset in |Buffer|.

◆ Cast()

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

◆ CopyContents()

size_t v8::ArrayBufferView::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 v8::ArrayBufferView::HasBuffer ( ) const

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