public class CssRule

extends Object

This is a helper class for building a StyleSheet by adding rules to it. Models a collection of rules, which are CSS attributes each mapped to a selector.

Purpose of this class is to build the hashmap of the rule and create a collection of selectors.

Here is an example of a rule with three selectors (h3, .label and .small), and a declaration (font-family:arial,helvetica,sans-serif;).

h3, .label, .small {font-family:arial,helvetica,sans-serif;}

See Also:

parse(String) for a detailed description of allowable syntax for rules. The selector names are case sensitive, even for the built-in HTML 2.0 selectors such as h1 and H1.

This class treats h1 and H1 as two different selectors.

Method Detail

main

public static void main(String[] args)
                 throws JspException

For testing only.

parse

public void parse(String str)
           throws JspException

Parse rule and return hashmap of selectors and declarations. More than one selector may share the declarations. Optional whitespace may be used anywhere between tokens. Multiple declarations must be separated by a comma. Declarations consist of pairs of property names and values. All but the last value must be terminated by a semi-colon.

Syntax is:

selector[, selector[, selector]...] { property:value[; property:value]...] }

For example: h1, h2,h3{color:red;font-size:10pt}

Embedded rules are not supported:

  three-dee {
   background-lighting {
     azimuth: 30deg;
     elevation: 190deg;
   }
   H1 { color: red }
 }

ruleToString

public String ruleToString()

Print the rule Hashmap so it conforms to css formatting. Duplicated in StyleSheet because I'm tired.

test

public void test()
          throws JspException

For testing only. Can be called from console.

toString

public String toString()

Format CssRule for printing

Overrides:

toString in class Object
