017/**
018 * A pairing of a {@link JsonSerializer} and {@link JsonParser} into a single class with convenience read/write methods.
019 *
020 * <p>
021 *    The general idea is to combine a single serializer and parser inside a simplified API for reading and writing POJOs.
022 *
023 * <h5 class='figure'>Examples:</h5>
024 * <p class='bcode w800'>
025 *    <jc>// Using instance.</jc>
026 *    Json json = <jk>new</jk> Json();
027 *    MyPojo myPojo = json.read(string, MyPojo.<jk>class</jk>);
028 *    String string = json.write(myPojo);
029 * </p>
030 * <p class='bcode w800'>
031 * <jc>// Using DEFAULT instance.</jc>
032 *    MyPojo myPojo = Json.<jsf>DEFAULT</jsf>.read(string, MyPojo.<jk>class</jk>);
033 *    String string = Json.<jsf>DEFAULT</jsf>.write(myPojo);
034 * </p>
