Interface TypeToken<T>

  • Type Parameters:
    T - type being supplied.

    Required to be present, though not used directly.

    All Superinterfaces:
    Supplier<Type>, TypeTokenSupplier<T>
    public interface TypeToken<T>
extends TypeTokenSupplier<T>
    A supplier that provides Type information. It can be used with generic classes in order to avoid "unchecked assignment" warnings.

    The following examples both create an instance of @{code Pair} class. 

    
      // Generates an "unchecked assignment" warning
      // which can be suppressed with @SuppressWarnings("unchecked")
      Pair<Integer, String> pair = Instancio.of(Pair.class)
          .withTypeParameters(Integer.class, String.class)
          .create();

     // This usage avoids the warning
     Pair<Integer, String> pair = Instancio.of(new TypeToken<Pair<Integer, String>>() {}).create();
