  org.jaudiotagger.tag.mp4.Mp4TagField
      org.jaudiotagger.tag.mp4.field.Mp4TagBinaryField

All Implemented Interfaces:

TagField

Direct Known Subclasses:

Mp4TagCoverField

public class Mp4TagBinaryField
extends Mp4TagField

Represents binary data

Subclassed by cover art field, TODO unaware of any other binary fields at the moment

Field Summary

protected int	dataSize
protected boolean	isBinary

Fields inherited from class org.jaudiotagger.tag.mp4.Mp4TagField

id, logger, parentHeader

Constructor Summary

Mp4TagBinaryField(java.lang.String id)
Construct an empty Binary Field

Mp4TagBinaryField(java.lang.String id, byte[] data)
Construct new binary field with binarydata provided

Mp4TagBinaryField(java.lang.String id, java.nio.ByteBuffer raw)
Construct binary field from rawdata of audio file

Method Summary

protected void	build(java.nio.ByteBuffer raw) Processes the data and sets the position of the data buffer to just after the end of this fields data ready for processing next field.
void	copyContent(TagField field) This method copies the data of the given field to the current data.
byte[]	getData()
protected byte[]	getDataBytes() Used when creating raw content
int	getDataSize()
Mp4FieldType	getFieldType()
boolean	isBinary() Determines whether the represented field contains (is made up of) binary data, instead of text data. Software can identify fields to be displayed because they are human readable if this method returns false.
boolean	isEmpty() Determines whether the content of the field is empty.
