Accessors

encryptionId

• get encryptionId(): number

Gets the encryption ID applied to the current instance.

Returns

number

Value containing the encryption identifier for the current instance or undefined if not set.

Inherited from

Frame.encryptionId

• set encryptionId(value): void

Sets the encryption ID applied to the current instance.

Parameters

Name	Type	Description
value	number	Value containing the encryption identifier for the current instance. Must be an 8-bit unsigned integer. Setting to undefined will remove the encryption header and ID

Returns

void

Inherited from

Frame.encryptionId

---

flags

• get flags(): Id3v2FrameFlags

Gets the frame flags applied to the current instance.

Returns

Id3v2FrameFlags

Inherited from

Frame.flags

• set flags(value): void

Sets the frame flags applied to the current instance. If the value includes either Encryption or Compression, render will throw.

Parameters

Name	Type
value	Id3v2FrameFlags

Returns

void

Inherited from

Frame.flags

---

frameClassType

• get frameClassType(): Id3v2FrameClassType

Gets a flag indicating which type of frame the current instance is.

Returns

Id3v2FrameClassType

Overrides

Frame.frameClassType

---

frameId

• get frameId(): Id3v2FrameIdentifier

Gets the frame ID for the current instance.

Returns

Id3v2FrameIdentifier

Object representing of the identifier of the frame

Inherited from

Frame.frameId

---

groupId

• get groupId(): number

Gets the grouping ID applied to the current instance.

Returns

number

Value containing the grouping identifier for the current instance, or undefined if not set.

Inherited from

Frame.groupId

• set groupId(value): void

Sets the grouping ID applied to the current instance.

Parameters

Name	Type	Description
value	number	Grouping identifier for the current instance. Must be an 8-bit unsigned integer. Setting to undefined will remove the grouping identity header and ID

Returns

void

Inherited from

Frame.groupId

---

header

• Protected get header(): Id3v2FrameHeader

Gets the header for the frame. For new frames this should not exist.

Returns

Id3v2FrameHeader

Inherited from

Frame.header

• Protected set header(value): void

Sets the header for the frame.

Parameters

Name	Type	Description
value	Id3v2FrameHeader	Header for the frame

Returns

void

Inherited from

Frame.header

---

playCount

• get playCount(): bigint

Gets the play count of the current instance.

Returns

bigint

• set playCount(value): void

Sets the play count of the current instance.

Parameters

Name	Type	Description
value	bigint	Number of times this track has been played

Returns

void

---

size

• get size(): number

Gets the size of the current instance as it was last stored on disk. NOTE: This value is not used outside of reading a frame from disk, so newly created frames should not have this value set.

Returns

number

Inherited from

Frame.size

Methods

clone

▸ clone(): Id3v2Frame

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

Id3v2Frame

Overrides

Id3v2Frame.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

Id3v2Frame.fieldData

---

parseFields

▸ Protected parseFields(data): 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

Returns

void

Overrides

Id3v2Frame.parseFields

---

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

Id3v2Frame.render

---

renderFields

▸ Protected renderFields(): ByteVector

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

Returns

ByteVector

Overrides

Id3v2Frame.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

Name	Type	Description
data	ByteVector	Raw ID3v2 frame
offset	number	Offset in data at which the frame begins.
readHeader	boolean	Whether or not to read the reader into the current instance.
version	number	Version of the ID3v2 tag the data was encoded with

Returns

void

Inherited from

Id3v2Frame.setData

---

correctEncoding

▸ Static Protected correctEncoding(type, version): StringType

Converts an encoding to be a supported encoding for a specified tag version.

Parameters

Name	Type	Description
type	StringType	Value containing the original encoding
version	number	Value containing the ID3v2 version to be encoded.

Returns

StringType

Value containing the correct encoding to use, based on forceDefaultEncoding and what is supported by version

Inherited from

Id3v2Frame.correctEncoding

---

fromEmpty

▸ Static fromEmpty(): Id3v2PlayCountFrame

Constructs and initializes a new instance with a count of zero

Returns

Id3v2PlayCountFrame

---

fromOffsetRawData

▸ Static fromOffsetRawData(data, offset, header, version): Id3v2PlayCountFrame

Constructs and initializes a new instance of frame by reading its raw data in a specified ID3v2 version starting at a specified offset.

Parameters

Name	Type	Description
data	ByteVector	Raw representation of the new frame.
offset	number	Offset into data where the frame actually begins. Must be a positive, safe integer
header	Id3v2FrameHeader	Header of the frame found at offset in the data
version	number	ID3v2 version the frame was originally encoded with

Returns

Id3v2PlayCountFrame

---

fromRawData

▸ Static fromRawData(data, version): Id3v2PlayCountFrame

Constructs and initializes a new instance by reading its raw data in a specified ID3v2 version

Parameters

Name	Type	Description
data	ByteVector	ByteVector starting with the raw representation of the new frame
version	number	ID3v2 version the raw frame is encoded in, must be a positive 8-bit integer

Returns

Id3v2PlayCountFrame
