Class Mp4TagRawBinaryField

java.lang.Object
  org.jaudiotagger.tag.mp4.Mp4TagField
      org.jaudiotagger.tag.mp4.field.Mp4TagRawBinaryField

All Implemented Interfaces:

TagField

public class Mp4TagRawBinaryField
extends Mp4TagField

Represents raw binary data

We use this when we find an atom under the ilst atom that we do not recognise , that does not follow standard conventions in order to save the data without modification so it can be safetly written back to file

Constructor Summary

Mp4TagRawBinaryField(Mp4BoxHeader header, java.nio.ByteBuffer raw)
Construct binary field from rawdata of audio file

Method Summary

protected void	build(java.nio.ByteBuffer raw) Build from data
void	copyContent(TagField field) This method copies the data of the given field to the current data.

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.

                     throws java.io.UnsupportedEncodingException

Construct binary field from rawdata of audio file

Parameters:

header -

raw -

Throws:

java.io.UnsupportedEncodingException

Method Detail

getFieldType

public Mp4FieldType getFieldType()

Specified by:

getFieldType in class Mp4TagField

Returns:

the field type of this field

getDataBytes

protected byte[] getDataBytes()
                       throws java.io.UnsupportedEncodingException

Used when creating raw content

Specified by:

getDataBytes in class Mp4TagField

Returns:

Throws:

java.io.UnsupportedEncodingException

build

protected void build(java.nio.ByteBuffer raw)

Build from data

After returning buffers position will be after the end of this atom

Specified by:

build in class Mp4TagField

Parameters:

raw -

isBinary

public boolean isBinary()

Description copied from interface: TagField

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.

Returns:

true if field represents binary data (not human readable).

isEmpty

public boolean isEmpty()

Description copied from interface: TagField

Determines whether the content of the field is empty.

Returns:

true if no data is stored (or empty String).

getDataSize

public int getDataSize()

getData

public byte[] getData()

setData

public void setData(byte[] d)

copyContent

public void copyContent(TagField field)

Description copied from interface: TagField

This method copies the data of the given field to the current data.

Parameters:

field - The field containing the data to be taken.

getRawContent

public byte[] getRawContent()
                     throws java.io.UnsupportedEncodingException

Description copied from class: Mp4TagField

Convert back to raw content, includes parent and data atom as views as one thing externally

Specified by:

getRawContent in interface TagField

Overrides:

getRawContent in class Mp4TagField

Returns:

Binary data representing the current tag field.

Throws:

java.io.UnsupportedEncodingException - Most tag data represents text. In some cases the underlying implementation will need to convert the text data in java to a specific charset encoding. In these cases an UnsupportedEncodingException may occur.
