Class Type<T>

  • Type Parameters:
    T -
    All Implemented Interfaces:
    Comparable<Type<?>>
    public final class Type<T>
extends Object
implements Comparable<Type<?>>
    Instances of this class map Java types to property types. Passing an instance of this class to PropertyState.getValue(Type) determines the return type of that method.
