Method Detail

stringForSACPrimitiveType

public static String stringForSACPrimitiveType(short type)

Given a unit constant like CSSPrimitiveValue.CSS_EMS will return the unit suffix like em. FIXME: Not exhaustive.

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. FIXME: Font proportional units are returned as absolute. Probably wrong method name rather than wrong behavior.

Parameters:

type - The CSSValue type to check.

Returns:

See desc.

isNumber

@Deprecated
public static boolean isNumber(short cssPrimitiveType)

Deprecated.

Only used by the broken DOMInspector.

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)?
