Class ParsedValue<V,T>

java.lang.Object
javafx.css.ParsedValue<V,T>
Type Parameters:
V - the type of the parsed value
T - the type of the converted value
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.

Since:
JavaFX 8.0
