Methods Summary
public java.lang.String[]	getCDataElements() Returns a list of all the elements whose text node children should be output as CDATA, or null if no such elements were specified. return _cdataElements;
public java.lang.String	getDoctypePublic() Returns the specified document type public identifier, or null. return _doctypePublic;
public java.lang.String	getDoctypeSystem() Returns the specified document type system identifier, or null. return _doctypeSystem;
public java.lang.String	getEncoding() Returns the specified encoding. If no encoding was specified, the default is always "UTF-8". return The encoding return _encoding;

public int	getIndent() Returns the indentation specified. If no indentation was specified, zero is returned and the document should not be indented. return The indentation or zero see #setIndenting return _indent;
public boolean	getIndenting() Returns true if indentation was specified. return ( _indent > 0 );
public char	getLastPrintable() Returns the last printable character based on the selected encoding. Control characters and non-printable characters are always printed as character references. if ( getEncoding() != null && ( getEncoding().equalsIgnoreCase( "ASCII" ) ) ) return 0xFF; else return 0xFFFF;
public java.lang.String	getLineSeparator() Returns a specific line separator to use. The default is the Web line separator (\n). A string is returned to support double codes (CR + LF). return The specified line separator return _lineSeparator;
public int	getLineWidth() Return the selected line width for breaking up long lines. When indenting, and only when indenting, long lines will be broken at space boundaries based on this line width. No line wrapping occurs if this value is zero. return _lineWidth;
public java.lang.String	getMediaType() Returns the specified media type, or null. To determine the media type based on the document type, use {@link #whichMediaType}. return The specified media type, or null return _mediaType;

public boolean	getPreserveSpace() Returns true if the default behavior for this format is to preserve spaces. All elements that do not specify otherwise or specify the default behavior will be formatted based on this rule. All elements that specify space preserving will always preserve space. return _preserve;
public boolean	getStandalone() Returns true if the document type is standalone. The default is false. return _standalone;
