  • Field Details

    • TYPE_DESCRIPTIONS

      private static final List<String> TYPE_DESCRIPTIONS
      Type descriptions--a crude approximation taken by scanning CSSValue statics

      public ValueConstants()
  • Method Details

    • cssType

      public static String cssType(int cssType, int primitiveValueType)
      A text representation of the CSS type for this value.
    • sacPrimitiveTypeForString

      public static short sacPrimitiveTypeForString(@Nullable String type)
    • stringForSACPrimitiveType

      public static String stringForSACPrimitiveType(short type)
    • 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.
    • 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.
    • getCssValueTypeDesc

      public static String getCssValueTypeDesc(CSSValue cssValue)
      Gets the cssValueTypeDesc attribute of the CSSValue object
    • 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)?
    • guessType

      public static short guessType(@Nullable String value)
      Incomplete routine to try and determine the CSSPrimitiveValue short code for a given value, e.g. 14pt is CSS_PT.
    • guessTypeByFont

      private static short guessTypeByFont(String value, String hmm)
