      public boolean isEmpty()

    • write

      public void write(int b) throws IOException
      Writes the specified byte to the underlying ByteChunk.
      Specified by:
      write in class OutputStream
      Parameters:
      b - the byte to be written.
      Throws:
      IOException

    • write

      public void write(@NotNull @org.jetbrains.annotations.NotNull byte[] b, int off, int len) throws IOException
      Writes len bytes from the specified byte array starting at offset off to the underlying ByteChunk.
      Overrides:
      write in class OutputStream
      Parameters:
      b - the data.
      off - the start offset in the data.
      len - the number of bytes to write.
      Throws:
      IndexOutOfBoundsException - if off is negative, len is negative, or len is greater than b.length - off
      IOException

    • size

    • getPayloadSize

      public long getPayloadSize(int sPos, int ePos)
      computes the size of the payload from sPos to ePos (inclusive)
      Parameters:
      sPos - the first data item to include in this payload

      Parameters:
      dos - the data output stream to populate with data
      sPos - the first data item to include in this payload
      ePos - the last data item to include in this payload
      Returns:
      number of bytes written to the outputstream
      Throws:
      IOException - if there is a problem writing to the output stream
