Example 82 with GenericArrayType

the class TypeToken method toGenericType.

/**
   * Returns the type token representing the generic type declaration of {@code cls}. For example:
   * {@code TypeToken.getGenericType(Iterable.class)} returns {@code Iterable<T>}.
   *
   * <p>If {@code cls} isn't parameterized and isn't a generic array, the type token of the class is
   * returned.
