            }
        }
        return value;
}

Fetches an integer attribute value. Attribute values are stored as a string, and this is a convenience method to convert to an actual integer.

 public static Tag getTag(String tagName) 
{
        Tag t =  tagHashtable.get(tagName);
        return (t == null ? null : t);
}

Fetches a tag constant for a well-known tag name (i.e. one of the tags in the set {A, ADDRESS, APPLET, AREA, B, BASE, BASEFONT, BIG, BLOCKQUOTE, BODY, BR, CAPTION, CENTER, CITE, CODE, DD, DFN, DIR, DIV, DL, DT, EM, FONT, FORM, FRAME, FRAMESET, H1, H2, H3, H4, H5, H6, HEAD, HR, HTML, I, IMG, INPUT, ISINDEX, KBD, LI, LINK, MAP, MENU, META, NOBR, NOFRAMES, OBJECT, OL, OPTION, P, PARAM, PRE, SAMP, SCRIPT, SELECT, SMALL, SPAN, STRIKE, S, STRONG, STYLE, SUB, SUP, TABLE, TD, TEXTAREA, TH, TITLE, TR, TT, U, UL, VAR}.

 static Tag getTagForStyleConstantsKey(StyleConstants sc) 
{
        return scMapping.get(sc);
}

Returns the HTML Tag associated with the StyleConstants key sc. If no matching Tag is found, returns null.
