Initializes a new instance with a specified GUID.

Parameters

Name	Type	Description
guid	UuidWrapper	GUID to use for the new instance.

Returns

void

Inherited from

---

render

▸ render(): ByteVector

Renders the current instance as a raw ASF object.

Returns

ByteVector

Overrides

AsfBaseObject.render

---

renderInternal

▸ Protected renderInternal(data): ByteVector

Renders the current instance as a raw ASF object containing the specified data.

Remarks

Child classes implementing () should render their contents and then send the data through this method to produce the final output.

Parameters

Name	Type	Description
data	ByteVector	Data to store in the rendered version of the current instance.

Returns

ByteVector
