Constructor Detail

AbstractID3v2

protected AbstractID3v2()

Creates a new AbstractID3v2 object.

AbstractID3v2

protected AbstractID3v2(AbstractID3v2 copyObject)

Creates a new AbstractID3v2 object.

Method Detail

setFrame

public void setFrame(AbstractID3v2Frame frame)

getFrame

public AbstractID3v2Frame getFrame(java.lang.String identifier)

getFrameCount

public int getFrameCount()

clearFrameMap

public void clearFrameMap()

getFrameIterator

public java.util.Iterator getFrameIterator()

getFrameOfType

public java.util.Iterator getFrameOfType(java.lang.String identifier)

hasFrame

public boolean hasFrame(java.lang.String identifier)

hasFrameOfType

public boolean hasFrameOfType(java.lang.String identifier)

iterator

public java.util.Iterator iterator()

Specified by:

iterator in class AbstractMP3Tag

removeFrame

public void removeFrame(java.lang.String identifier)

removeFrameOfType

public void removeFrameOfType(java.lang.String identifier)

values

public java.util.Collection values()

append

public void append(AbstractMP3Tag abstractMP3Tag)

Description copied from class: AbstractMP3Tag

This method does nothing, but is called by subclasses for completeness

Specified by:

append in class AbstractMP3Tag

Parameters:

abstractMP3Tag - tag to overwrite

append

public void append(java.io.RandomAccessFile file)
            throws java.io.IOException,
                   TagException

Description copied from class: AbstractMP3Tag

Appends this tag to the given file. Append means any information this tag contains will be added to the file's corresponding tag, but it will not replace any fields that the file already has. If the file does not have this specific tag, a new one will be created.

Specified by:

append in class AbstractMP3Tag

Parameters:

file - MP3 file to append to.

Throws:

TagException - on any exception generated by this library.

java.io.IOException - on any I/O error

delete

public void delete(java.io.RandomAccessFile file)
            throws java.io.IOException

Description copied from class: AbstractMP3Tag

removes the specific tag the easiest way.
ID3v1 - cuts the length of the tag
lyrics3 -cuts the length of the tag, then writes the id3v1 tag if it existed
id3v2 - just overwrites the ID3 tag indicator at the start of the tag

Specified by:

delete in class AbstractMP3Tag

Parameters:

file - MP3 file to append to.

Throws:

java.io.IOException - on any I/O error

equals

public boolean equals(java.lang.Object obj)

Description copied from class: AbstractMP3Tag

Determines whether another object is equal to this tag. It just compares if they are the same class, then calls super.equals(object).

Overrides:

equals in class AbstractMP3Tag

overwrite

public void overwrite(AbstractMP3Tag abstractMP3Tag)

Description copied from class: AbstractMP3Tag

This method does nothing, but is called by subclasses for completeness

Specified by:

overwrite in class AbstractMP3Tag

Parameters:

abstractMP3Tag - tag to overwrite

overwrite

public void overwrite(java.io.RandomAccessFile file)
               throws java.io.IOException,
                      TagException

Description copied from class: AbstractMP3Tag

Overwrites this tag to the given file. Overwrite means any information this tag contains will replace any existing fields in the file's corresponding tag. If the file does not have this specific tag, a new one will be created.

Specified by:

overwrite in class AbstractMP3Tag

Parameters:

file - MP3 file to overwrite

Throws:

java.io.IOException - on any I/O error

TagException - on any exception generated by this library.
