Class CssObjectDeclarationParser

java.lang.Object
  echopointng.stylesheet.CssObjectDeclarationParser

public class CssObjectDeclarationParser
extends java.lang.Object

CssObjectDeclarationParser takes CSS object declarations and parse them into their value parts. A CSS object declaration is defined as

 cssobjectdecl  ::= <identifier> '(' <cssobjectvaleq> ')'
 
 cssobjectvaleq ::=     <cssobjectval> { "," cssobjectval }
 
 cssobjectval   ::=   <cssobjectdecl> ||
                      <anystring>  
 

An CSS object declaration can contain child declarations as in

       fillimage(image('imageurl',12px,12px),repeat);
 

This parser only returns the top level values of the outer CSS object declarations. You will need to "reparse" child declarations as required. So in the above example the parser will return the strings :

       "fillimage" "image('imageurl',12px,12px)" "repeat"
 

The object type name will always be in the first array element. In the above example "fillimage" is the object type name.
