javafx.css.ParsedValue<V,T>
public class ParsedValue<V,T> extends Object
A representation of a parsed CSS value.
V
is the type of the parsed
value, T
is the StyleableProperty
type of the converted value.
Instances of ParsedValue
are created by the CSS parser. For example,
the parser creates a ParsedValue<String,Color>
when it parses a
web Color.
A ParsedValue is meaningful to the code that calculates actual values from
parsed CSS values. Elsewhere the value returned by
getValue()
is likely to be obscure, abstruse and perplexing.

is null, then it is assumed that the type of valueV
and the type of targetT
are the same and do not need converted.- Parameters:
