org.cometd.bayeux.BinaryData

All Implemented Interfaces:

Serializable, Cloneable, Map<String,Object>

public class BinaryData
extends HashMap<String,Object>

Reified representation of binary data chunk contained in a message.

BinaryData is composed of a metaData map that contains application information about the binary chunk (such as a file name, the mime type, or the chunk number), of the binary chunk itself (either in byte[] or ByteBuffer format), and of the boolean last flag indicating whether it is the last chunk.
