Constructor Detail

CmsHtmlConverter

public CmsHtmlConverter()

Constructor, creates a new CmsHtmlConverter.

The encoding used by default is CmsEncoder.ENCODING_UTF_8.

CmsHtmlConverter

public CmsHtmlConverter(java.lang.String encoding,
                        java.lang.String mode)

Constructor, creates a new CmsHtmlConverter.

Possible values for the default conversion mode are:

• PARAM_DISABLED: The conversion is disabled.
• PARAM_ENABLED: Conversion is enabled without transformation, so HTML is pretty printed only.
• PARAM_XHTML: Conversion from HTML to XHTML is enabled.
• PARAM_WORD: Cleanup of word like HTML tags is enabled.
• Other values can be used by the implementing converter class.

Values can be combined with the ; separator, so it is e.g. possible to convert to XHTML and clean from word at the same time.

Parameters:

encoding - the encoding used for the HTML code conversion

mode - the conversion mode to use
