   * <h5 class='topic'>Valid data conversions</h5>
   * <p>
   * Parsers can parse any parsable POJO types, as specified in the <a class="doclink" href="https://juneau.apache.org/docs/topics/PojoCategories">POJO Categories</a>.
   *
   * <p>
   * Some examples of conversions are shown below...

  * 	</tr>
  * </table>
  *
  * <p>
  * In addition, any class types with {@link ObjectSwap ObjectSwaps} associated with them on the registered
  * bean context can also be passed in.
  *
  * <p>
  * For example, if the {@link TemporalCalendarSwap} transform is used to generalize {@code Calendar} objects to {@code String}
  * objects.
  * When registered with this parser, you can construct {@code Calendar} objects from {@code Strings} using the
  * following syntax...
  * <p class='bjava'>
  * 	Calendar <jv>calendar</jv> = <jv>parser</jv>.parse(<js>"'Sun Mar 03 04:05:06 EST 2001'"</js>, GregorianCalendar.<jk>class</jk>);
  * </p>
  *
  * <p>
  * If <code>Object.<jk>class</jk></code> is specified as the target type, then the parser automatically determines the
  * data types and generates the following object types...
  * <table class='styled'>
  * 	<tr><th>JSON type</th><th>Class type</th></tr>
  * 	<tr><td>object</td><td>{@link JsonMap}</td></tr>
  * 	<tr><td>array</td><td>{@link JsonList}</td></tr>
  * 	<tr><td>number</td><td>{@link Number}<br>(depending on length and format, could be {@link Integer},
  * 		{@link Double}, {@link Float}, etc...)</td></tr>
  * 	<tr><td>boolean</td><td>{@link Boolean}</td></tr>
  * 	<tr><td>string</td><td>{@link String}</td></tr>
