  org.jaudiotagger.tag.mp4.Mp4TagField
      org.jaudiotagger.tag.mp4.field.Mp4TagTextField
          org.jaudiotagger.tag.mp4.field.Mp4TagByteField

All Implemented Interfaces:

TagField, TagTextField

public class Mp4TagByteField
extends Mp4TagTextField

Represents a single byte as a number

Usually single byte fields are used as a boolean field, but not always so we dont do this conversion

Field Summary

private byte[]	bytedata
private int	realDataLength
static java.lang.String	TRUE_VALUE

Fields inherited from class org.jaudiotagger.tag.mp4.field.Mp4TagTextField

content, dataSize

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

id, logger, parentHeader

Constructor Summary

Mp4TagByteField(Mp4FieldKey id, java.lang.String value)
Create new field

Assume length of 1 which is correct for most but not all byte fields

Mp4TagByteField(Mp4FieldKey id, java.lang.String value, int realDataLength)
Create new field with known length

Mp4TagByteField(java.lang.String id, java.nio.ByteBuffer raw)
Construct from rawdata from audio file

Method Summary

protected void	build(java.nio.ByteBuffer data) 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.
protected byte[]	getDataBytes() Return raw data bytes TODO this code should be done better so generalised to any length
