Re: [v8-users] Arraybuffer

[dan Med]

I don't have understood this part, let me explain it to you.
This is how i get it tell me if i'm wrong at any part.

I need to understand how is the structure in memory of the arraybuffer how
is it represented and if the data of the array are directly stored at an
offset accessed by buffer_ -> data().


before the call to expand capacity it does create an array


the arraybuffer in src /third_party
/blink
/renderer
/platform
/
wtf

/typed_arrays

/array_buffer_builder.cc

is
called whenever the renderer  (has to execute some javascript which defines
arraybuffers)
First when is arraybuffer::append  called, cause i know that if someone
need to reallocate a bigger arraybuffer then a new instance will be created
and filled with the old values if the length in the original array isn't
has much as the user reqeusted ?

One more thing is, when this class is called, the arraybuffer is always set
to the initial length of static const int kDefaultBufferCapacity

= 32768; if in the javascript i declare an arraybuffer of 20bytes will it
allocate of
32768bytes anyway =?
