protected String

id

Constructor Summary

Mp4TagField(String id)

Mp4TagField(String id, byte[] raw)

Method Summary

protected abstract void	build(byte[] raw)
String	getId() Returns the Id of the represented tag field. This value should uniquely identify a kind of tag data, like title.
protected byte[]	getIdBytes()
void	isBinary(boolean b) This method will set the field to represent binary data. Some implementations may support conversions. As of now (Octobre 2005) there is no implemenation really using this method to perform useful operations.
boolean	isCommon() Identifies a field to be of common use. Some software may differ between common and not common fields.

Method Detail

getId

public String getId()

Description copied from interface: TagField

Returns the Id of the represented tag field.
This value should uniquely identify a kind of tag data, like title. AbstractTag will use the "id" to summarize multiple fields.

Specified by:

getId in interface TagField

Returns:

Unique identifier for the fields type. (title, artist...)

isBinary

public void isBinary(boolean b)

Description copied from interface: TagField

This method will set the field to represent binary data.
Some implementations may support conversions.
As of now (Octobre 2005) there is no implemenation really using this method to perform useful operations.

Specified by:

isBinary in interface TagField

Parameters:

b - true, if the field contains binary data.

isCommon

public boolean isCommon()

Description copied from interface: TagField

Identifies a field to be of common use.
Some software may differ between common and not common fields. A common one is for sure the title field. A web link may not be of common use for tagging. However some file formats, or future developement of users expectations will make more fields common than now can be known.

Specified by:

isCommon in interface TagField

Returns:

true if the field is of common use.

getIdBytes

protected byte[] getIdBytes()

build

protected abstract void build(byte[] raw)
                       throws UnsupportedEncodingException

Throws:

UnsupportedEncodingException
