      Modifier and Type Method Description
      static String cssType​(int cssType, int primitiveValueType)
      A text representation of the CSS type for this value.
      static String getCssValueTypeDesc​(CSSValue cssValue)
      Gets the cssValueTypeDesc attribute of the CSSValue object
      static short guessType​(String value)
      Incomplete routine to try and determine the CSSPrimitiveValue short code for a given value, e.g.
      static boolean isAbsoluteUnit​(short type)
      Returns true if the specified type absolute (even if we have a computed value for it), meaning that either the value can be used directly (e.g.
      static boolean isAbsoluteUnit​(CSSPrimitiveValue primitive)
      Returns true if the specified value was absolute (even if we have a computed value for it), meaning that either the value can be used directly (e.g.
      static boolean isNumber​(short cssPrimitiveType)
      Returns true if the SAC primitive value type is a number unit--a unit that can only contain a numeric value.

        public static String cssType​(int cssType,
                             int primitiveValueType)
        A text representation of the CSS type for this value.
        Parameters:
        cssType - PARAM
        primitiveValueType - PARAM
        Returns:
        Returns

      • sacPrimitiveTypeForString

        public static short sacPrimitiveTypeForString​(String type)
        Description of the Method
        Parameters:
        type - PARAM
        Returns:
        Returns

      • stringForSACPrimitiveType

        public static String stringForSACPrimitiveType​(short type)
        Description of the Method
        Parameters:
        type - PARAM
        Returns:
        Returns

      • isAbsoluteUnit

        public static boolean isAbsoluteUnit​(CSSPrimitiveValue primitive)
        Returns true if the specified value was absolute (even if we have a computed value for it), meaning that either the value can be used directly (e.g. pixels) or there is a fixed context-independent conversion for it (e.g. inches). Proportional types (e.g. %) return false.
        Parameters:
        primitive - The CSSValue instance to check.
        Returns:
        See desc.

      • isAbsoluteUnit

        public static boolean isAbsoluteUnit​(short type)
        Returns true if the specified type absolute (even if we have a computed value for it), meaning that either the value can be used directly (e.g. pixels) or there is a fixed context-independent conversion for it (e.g. inches). Proportional types (e.g. %) return false.
        Parameters:
        type - The CSSValue type to check.
        Returns:
        See desc.

      • getCssValueTypeDesc

        public static String getCssValueTypeDesc​(CSSValue cssValue)
        Gets the cssValueTypeDesc attribute of the CSSValue object
        Parameters:
        cssValue - PARAM
        Returns:
        The cssValueTypeDesc value

      • isNumber

        public static boolean isNumber​(short cssPrimitiveType)
        Returns true if the SAC primitive value type is a number unit--a unit that can only contain a numeric value. This is a shorthand way of saying, did the user declare this as a number unit (like px)?
        Parameters:
        cssPrimitiveType - PARAM
        Returns:
        See desc.

      • guessType

        public static short guessType​(String value)
        Incomplete routine to try and determine the CSSPrimitiveValue short code for a given value, e.g. 14pt is CSS_PT.
        Parameters:
        value - PARAM
