Method from org.w3c.css.sac.LexicalUnit Detail:
 public String getDimensionUnitText()
    Returns the string representation of the unit.

    if this lexical unit represents a float, the dimension is an empty
string.
 public float getFloatValue()
    Returns the float value.

    If the type of LexicalUnit is one of SAC_DEGREE,
SAC_GRADIAN, SAC_RADIAN, SAC_MILLISECOND, SAC_SECOND, SAC_HERTZ
or SAC_KILOHERTZ, the value can never be negative.
 public String getFunctionName()
    Returns the name of the function.
 public int getIntegerValue()
    Returns the integer value.
 public short getLexicalUnitType()
    An integer indicating the type of LexicalUnit.
 public LexicalUnit getNextLexicalUnit()
    Returns the next value or null if any.
 public LexicalUnit getParameters()
    The function parameters including operators (like the comma).
#000 is converted to rgb(0, 0, 0)
can return null if SAC_FUNCTION.
 public LexicalUnit getPreviousLexicalUnit()
    Returns the previous value or null if any.
 public String getStringValue()
    Returns the string value.

    If the type is SAC_URI, the return value doesn't contain
uri(....) or quotes.

    If the type is SAC_ATTR, the return value doesn't contain
