Method Detail

getInstance

public static Transcoder getInstance(String key)
                              throws ClassNotFoundException,
                                     InstantiationException,
                                     IllegalAccessException,
                                     NoSuchMethodException,
                                     InvocationTargetException

Throws:

ClassNotFoundException

InstantiationException

IllegalAccessException

NoSuchMethodException

InvocationTargetException

init

public void init(Node dest)

Description copied from interface: Transcoder

Init the transcoder and destination node with appropiate values.

Specified by:

init in interface Transcoder

Parameters:

dest - stream destination Node

setFormat

public void setFormat(String f)

getFormat

public Format getFormat()

Specified by:

getFormat in interface Transcoder

setCodec

public void setCodec(String c)

getCodec

public Codec getCodec()

Specified by:

getCodec in interface Transcoder

getMimeType

public MimeType getMimeType()

setMimeType

public void setMimeType(String m)

getKey

public String getKey()

Default and generic implementation of the key. It can be parsed back to the same transcoder instance with getInstance(java.lang.String). This makes for a key which is, like the icaches 'ckey' key unique and parseable. The implementation depends on Settings annotations to be set on the classes.

Specified by:

getKey in interface Transcoder

transcode

public void transcode(URI in,
                      URI out,
                      Logger log)
               throws Exception

Description copied from interface: Transcoder

Transcode a file to another, follow the process with a logger.

Specified by:

transcode in interface Transcoder

Throws:

Exception

transcode

protected abstract void transcode(Logger log)
                           throws Exception

Throws:

Exception

toString

public String toString()

Overrides:

toString in class Object

getIn

public URI getIn()

Specified by:

getIn in interface Transcoder

getOut

public URI getOut()

Specified by:

getOut in interface Transcoder

clone

public AbstractTranscoder clone()

Specified by:

clone in interface PublicCloneable<Transcoder>

Overrides:

clone in class Object
