/**
 * <p>General purpose data type converter that can be registered and used
 * within the BeanUtils package to manage the conversion of objects from
 * one type to another.</p>
 *
 * <p>Converter subclasses bundled with the BeanUtils library are required
 * to be thread-safe, as users of the library may call conversion methods
 * from more than one thread simultaneously.</p>
 *
 * <p>Custom converter subclasses created by users of the library can be
 * non-thread-safe if the application using them is single-threaded. However
 * it is recommended that they be written in a thread-safe manner anyway.</p>
