Method Detail

cssType

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(org.w3c.dom.css.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(org.w3c.dom.css.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

Returns:

Returns
