Method Detail

getAllTags

public static HTML.Tag[] getAllTags()
Returns the set of actual HTML tags that are recognized by the default HTML reader. This set does not include tags that are manufactured by the reader.


getTag

public static HTML.Tag getTag(String tagName)
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}. If the given name does not represent one of the well-known tags, then null will be returned.

Parameters:
tagName - the String name requested
Returns:
a tag constant corresponding to the tagName, or null if not found

getTagForStyleConstantsKey

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

Parameters:
sc - the StyleConstants key
Returns:
tag which corresponds to sc, or null if not found

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

Parameters:
attr - the set of attributes to use to try to fetch a value
key - the key to use to fetch the value
def - the default value to use if the attribute isn't defined or there is an error converting to an integer
