Class BinaryData

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, java.util.Map<java.lang.String,java.lang.Object>

    public class BinaryData
    extends java.util.HashMap<java.lang.String,java.lang.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.
