Constructor
new BufferUtils()
A set of BufferSource utility functions.

Methods
equal(arr1nullable, arr2nullable) → {boolean}
Compare two buffers for equality. For buffers of different types, this
compares the underlying buffers as binary data.
Parameters:
| Name | Type | Attributes | Description |
|---|---|---|---|
arr1 |
BufferSource |
<nullable> |
|
arr2 |
BufferSource |
<nullable> |
- Source:
Returns:
- Type
- boolean
toArrayBuffer(viewnon-null) → {ArrayBuffer}
Gets an ArrayBuffer that contains the data from the given TypedArray. Note
this will allocate a new ArrayBuffer if the object is a partial view of
the data.
Parameters:
| Name | Type | Description |
|---|---|---|
view |
BufferSource |
- Source:
Returns:
- Type
- ArrayBuffer
toDataView(buffer, offsetopt, lengthopt) → {DataView}
Creates a DataView over the given buffer.
Parameters:
| Name | Type | Attributes | Default | Description |
|---|---|---|---|---|
buffer |
BufferSource | |||
offset |
number |
<optional> |
0 | |
length |
number |
<optional> |

- toUint8
Returns:
- Type
- DataView
toUint8(data, offsetopt, lengthopt) → {Uint8Array}
Creates a new Uint8Array view on the same buffer. This clamps the values
to be within the same view (i.e. you can't use this to move past the end
of the view, even if the underlying buffer is larger). However, you can
pass a negative offset to access the data before the view.
Parameters:
| Name | Type | Attributes | Default | Description |
|---|---|---|---|---|
data |
BufferSource | |||
offset |
number |
<optional> |
0 | The offset from the beginning of this data's view to start the new view at. |
length |
number |
<optional> |
The byte length of the new view. |
- Source:
Returns:
- Type
- Uint8Array
toUint16(data, offsetopt, lengthopt) → {Uint16Array}
Creates a new Uint16Array view on the same buffer. This clamps the values
to be within the same view (i.e. you can't use this to move past the end
of the view, even if the underlying buffer is larger). However, you can
pass a negative offset to access the data before the view.
Parameters:
| Name | Type | Attributes | Default | Description |
|---|---|---|---|---|
data |
BufferSource | |||
offset |
number |
<optional> |
0 | The offset from the beginning of this data's view to start the new view at. |
length |
number |
<optional> |
The byte length of the new view. |

Returns:
- Type
- Uint16Array
unsafeGetArrayBuffer_(view) → {ArrayBuffer}
Gets the underlying ArrayBuffer of the given view. The caller needs to
ensure it uses the "byteOffset" and "byteLength" fields of the view to
only use the same "view" of the data.
Parameters:
| Name | Type | Description |
|---|---|---|
view |
BufferSource |
- Source:
Returns:
- Type
- ArrayBuffer
view_(data, offset, length, Type) → {T}
Parameters:
| Name | Type | Description |
|---|---|---|
data |
BufferSource | |
offset |
number | |
length |
number | |
Type |
function(new:T, ArrayBuffer, number, number) |
