Methods

clone

▸ clone(): Id3v2UserUrlLinkFrame

Creates a deep copy of the current instance. This method is implemented by rendering the current instance as an ID3v2.4 frame and using the frame factory to create a new frame. As such, this method should be overridden by child classes.

Returns

Id3v2UserUrlLinkFrame

Overrides

Id3v2UrlLinkFrame.clone

---

fieldData

▸ Protected fieldData(frameData, offset, version, dataIncludesHeader): ByteVector

Extracts the field data from the raw portion of an ID3v2 frame. This method is necessary for extracting extra data prepended to the frame such the as grouping ID.

Parameters

Name	Type	Description
frameData	ByteVector	Raw frame data
offset	number	Index at which the data is contained
version	number	Version of the ID3v2 tag the data was originally encoded with
dataIncludesHeader	boolean	true if frameData includes the header, false otherwise

Returns

ByteVector

Inherited from

Id3v2UrlLinkFrame.fieldData

---

parseFields

▸ Protected parseFields(data, version): void

Populates the values in this frame by parsing its field data in a specified version.

Parameters

Name	Type	Description
data	ByteVector	Extracted field data
version	number	ID3v2 version the field data is encoded in

Returns

void

Inherited from

Id3v2UrlLinkFrame.parseFields

---

parseRawData

▸ Protected parseRawData(): void

Performs the actual parsing of the raw data.

Remarks

Because of the high parsing cost and relatively low usage of the class, parseFields only stores the field data, so it can be parsed on demand. Whenever a property or method is called which requires the data, this method is called, and only on the first call does it actually parse the data.

Returns

void

Inherited from

Id3v2UrlLinkFrame.parseRawData

---

render

▸ render(version): ByteVector

Renders the current instance, encoded in a specified ID3v2 version.

Parameters

Name	Type	Description
version	number	Version of ID3v2 to use when encoding the current instance

Returns

ByteVector

Inherited from

Id3v2UrlLinkFrame.render

---

renderFields

▸ Protected renderFields(version): ByteVector

Renders the values in the current instance into field data for a specified version.

Parameters

Returns

ByteVector

Inherited from

Id3v2UrlLinkFrame.renderFields

---

setData

▸ Protected setData(data, offset, readHeader, version): void

Populates the current instance by reading the raw frame from disk, optionally reading the header.

Parameters
