Method Detail

### createValue

    public Value createValue(org.w3c.css.sac.LexicalUnit lu,
                             CSSEngine engine)
                      throws org.w3c.dom.DOMException

  Implements `ValueManager.createValue(LexicalUnit,CSSEngine)`.

  Parameters:
    `lu` - The SAC lexical unit used to create the value.
    `engine` - The calling CSSEngine.
  Throws:
    `org.w3c.dom.DOMException`

### createFloatValue

    public Value createFloatValue(short type,
                                  float floatValue)
                           throws org.w3c.dom.DOMException

  Implements `ValueManager.createFloatValue(short,float)`.

  Specified by:
    `createFloatValue` in interface `ValueManager`
  Overrides:
    `createFloatValue` in class `AbstractValueManager`
  Parameters:
    `type` - A unit code as defined above. The unit code can only be a float unit type
    `floatValue` - The new float value.
  Throws:
    `org.w3c.dom.DOMException`

### computeValue

    public Value computeValue(CSSStylableElement elt,
                              java.lang.String pseudo,
                              CSSEngine engine,
