      void discard()
      Frees temporarily allocated resources such as temporary file, buffer, etc.
      boolean equals​(java.lang.Object obj)
      Default implementation of the equals method.
      javax.jcr.Binary getBinary()
      This implementation creates a binary instance that uses QValue.getStream() and skipping on the given stream as its underlying mechanism to provide random access defined on Binary.
