Constructor Detail

ID3v2ExtendedHeader

public ID3v2ExtendedHeader()

Creates an extended header with preferences

ID3v2ExtendedHeader

public ID3v2ExtendedHeader(boolean use_crc,
                           int crc,
                           int padding_size)

Creates an extended header

Parameters:

use_crc - Use CRC?

crc - CRC of frames (will be set to 0 if use_crc== false)

padding_size - Size of padding

ID3v2ExtendedHeader

public ID3v2ExtendedHeader(java.io.InputStream in)
                    throws java.io.IOException

Creates an extended header from a stream. Stream must be positioned to the first byte of the extended header.

Parameters:

in - Stream to read from

Throws:

java.io.IOException - If an I/O error occurs

Method Detail

getSize

public int getSize()

Returns:

Size of extended header

getPaddingSize

public int getPaddingSize()

Returns:

Size of padding

setPaddingSize

public void setPaddingSize(int size)

Set size of padding

Parameters:

size - Size of padding

hasCRC

public boolean hasCRC()

Returns:

true if CRC is used

setHasCRC

public void setHasCRC(boolean crc)

Set if CRC is used

Parameters:

crc - True: CRC is used

getCRC

public long getCRC()

Returns:

CRC stored in extended header

setCRC

public void setCRC(int crc)

Set CRC. This automatically sets hasCRC to return true.

Parameters:

crc - CRC to set

getBytes

public byte[] getBytes()

Returns an array of bytes representing this extended header.

Note: This is not unsynchronized!

Returns:

Extended header as bytes, ready to write
