Method Summary

long	getCurrentAsfChunkSize() This method calculates the total amount of bytes, the chunk would consume in an ASF file.
GUID	getGuid() Returns the GUID of the chunk.
boolean	isEmpty() true if it is not necessary to write the chunk into an ASF file, since it contains no information.
long	writeInto(java.io.OutputStream out) Writes the chunk into the specified output stream, as ASF stream chunk.

Method Detail

getCurrentAsfChunkSize

long getCurrentAsfChunkSize()

This method calculates the total amount of bytes, the chunk would consume in an ASF file.

Returns:

amount of bytes the chunk would currently need in an ASF file.

getGuid

GUID getGuid()

Returns the GUID of the chunk.

Returns:

GUID of the chunk.

isEmpty

boolean isEmpty()

true if it is not necessary to write the chunk into an ASF file, since it contains no information.
