                                   java.lang.StringBuilder textBuffer)
                            throws java.io.IOException

      Description copied from class: `PDFObject`
      Writes a "direct object" (inline object) representation to the stream. A text buffer is given for optimized encoding of text content.

      IMPORTANT: If you need to write out binary output, call `PDFDocument.flushTextBuffer(StringBuilder, OutputStream)` before writing any content to the `OutputStream`!

      Specified by:
        `outputInline` in interface `PDFWritable`
      Overrides:
        `outputInline` in class `PDFObject`
      Parameters:
        `out` - the OutputStream (for binary content)
        `textBuffer` - the text buffer for text content
      Throws:
        `java.io.IOException` - if an I/O error occurs

    - #### getObjectNumber

          public PDFObjectNumber getObjectNumber()

      Returns the object number of this indirect object. Note that a compressed object must have a generation number of 0.
      Returns:
        the object number.

    - #### output

          public int output(java.io.OutputStream outputStream)
                     throws java.io.IOException

      Outputs this object's content into the given stream.
      Parameters:
        `outputStream` - a stream, likely to be provided by the containing object stream
      Returns:
        the number of bytes written to the stream
      Throws:
        `java.io.IOException`
