Usage

From source file:com.dubic.codesnippets.application.GsonMessageConverter.java

/**
 * Return the Gson {@link TypeToken} for the specified type.
 * <p>/* w w w  .  j  a  va 2 s. co  m*/
 * The default implementation returns {@code TypeToken.get(type)}, but this
 * can be overridden in subclasses to allow for custom generic collection
 * handling. For instance:
 * <pre class="code">
 * protected TypeToken<?> getTypeToken(Type type) { if (type instanceof
 * Class && List.class.isAssignableFrom((Class<?>) type)) { return new
 * TypeToken<ArrayList<MyBean>>() {}; } else { return
 * super.getTypeToken(type); } }
 * </pre>
 *
 * @param type the type for which to return the TypeToken
 * @return the type token
 */
protected TypeToken<?> getTypeToken(Type type) {
    return TypeToken.get(type);
