Constructor Detail

RobustMovieDecoder

public RobustMovieDecoder()

Method Detail

setDecodeRule

public void setDecodeRule(int decodeRule)

Parameters:

decodeRule - the robustness level to use for re-aligning the decoder. MovieDecoder just chokes if a given tag has trailing data - does not need as many bytes as it declares it has. This decorator will attempt to realign by either: 1) LAX - chewing up *any* bytes to realign 2) NULLS - chewing up only trailing NULL bytes trailing the tag 3) STRICT - throw exception if an realignment is required.

setDelegate

public void setDelegate(com.flagstone.transform.coder.SWFFactory<com.flagstone.transform.MovieTag> delegate)

Parameters:

delegate - the underlying/wrapped MovieDecoder which does the heavy lifting to parse out tags.

getObject

public void getObject(List<com.flagstone.transform.MovieTag> list,
                      com.flagstone.transform.coder.SWFDecoder coder,
                      com.flagstone.transform.coder.Context context)
               throws IOException

Specified by:

getObject in interface com.flagstone.transform.coder.SWFFactory<com.flagstone.transform.MovieTag>

Throws:

IOException
