    - #### hasCode

          public boolean hasCode()

      Indicates if the last text fragment passed to `separateCodesFromText(TextFragment)` has codes or not.
      Returns:
        true if the fragment has one or more code, false if it does not.

    - #### separateCodesFromText

          public java.lang.String separateCodesFromText(TextFragment frag)

      Separate and store codes of a given text fragment.
      Parameters:
        `frag` - the fragment to process. Use `createNewFragmentWithCodes(String)` to reconstruct the text back with its codes at the end.
      Returns:
        the fragment content stripped of its codes.

    - #### createNewFragmentWithCodes

          public TextFragment createNewFragmentWithCodes(java.lang.String plainText)

      Appends the codes stored apart using `separateCodesFromText(TextFragment)` at the end of a given plain text. The text fragment provided must be the same and without code modifications, as the one used for the splitting.
      Parameters:
        `plainText` - new text to use (must be plain)
      Returns:
        the provided fragment, but with the new text and the original codes appended at the end.

    - #### toCodedHTML

          public java.lang.String toCodedHTML(TextFragment fragment)

      Converts from coded text to coded HTML. The resulting string is also valid XML.
      Parameters:
        `fragment` - the fragment to convert.
      Returns:
        The resulting HTML string.

    - #### fromCodedHTMLToFragment

          public TextFragment fromCodedHTMLToFragment(java.lang.String text,
                                             TextFragment fragment)

      Converts an HTML string created with `toCodedHTML(TextFragment)` back into a text fragment, but with empty inline codes.
      Parameters:
        `text` - the HTML string to convert.
        `fragment` - an optional text fragment where to place the converted content. Any existing codes will be replaced or removed by the codes coming from the HTML string. Use null to create a new fragment.
      Returns:
        the modified or created text fragment.

    - #### fromCodedHTML

          public java.lang.String fromCodedHTML(java.lang.String htmlText,

                                       boolean addMissingCodes)

      Converts back a coded HTML to a coded text. (extra span elements are removed).
      Parameters:

        `fragment` - the original text fragment.
        `addMissingCodes` - true to added codes that are in the original fragment but not in the HTML string.
      Returns:
        the coded text with its code markers.

    - #### fromCodedHTML
