Properties

HEADER_LENGTH

▪ Static Readonly HEADER_LENGTH: 24

Length of the padding object header in bytes.

Accessors

guid

• get guid(): UuidWrapper

Gets the GUID that identifies the current instance.

Returns

UuidWrapper

Inherited from

BaseObject.guid

---

objectType

• get objectType(): AsfObjectType

Gets the type of the object for easy comparison.

Returns

AsfObjectType

Overrides

BaseObject.objectType

---

originalSize

• get originalSize(): number

Gets the original size of the current instance.

Returns

number

Inherited from

BaseObject.originalSize

---

size

• get size(): number

Gets the number of bytes the current instance will take up on disk. Note: this does not include the header for the object.

Returns

number

• set size(value): void

Sets the number of padding bytes the current instance will contain. Note: this does not include the header for the object.

Parameters

Name	Type	Description
value	number	Size of the current instance in bytes, must be a safe, positive integer.

Returns

void

Methods

initializeFromFile

▸ Protected initializeFromFile(file, position): void

Initializes a new instance by reading the contents from a specified position in a specified file.

Parameters

Name	Type	Description
file	File	File which contains the details of the new instance to create
position	number	Position in file where the object begins

Returns

void

Inherited from

AsfBaseObject.initializeFromFile

---

initializeFromGuid

▸ Protected initializeFromGuid(guid): void

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

AsfBaseObject.initializeFromGuid

---

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

Inherited from

AsfBaseObject.renderInternal

---

fromFile

▸ Static fromFile(file, position): AsfPaddingObject

Constructs and initializes a new instance by reading it from a file.

Parameters

Name	Type	Description
file	File	File to read the padding object from
position	number	Index into the file where the padding object starts from

Returns

AsfPaddingObject

---

fromSize

▸ Static fromSize(size): AsfPaddingObject

Constructs and initializes a new instance with a fixed size.

Parameters

Name	Type	Description
size	number	Number of padding bytes to store in the object not including the size of the header

Returns

AsfPaddingObject
