/**
* Controls String formatting for {@link ToStringBuilder}.
* The main public interface is always via ToStringBuilder.
*
* These classes are intended to be used as Singletons.
* There is no need to instantiate a new style each time. A program
* will generally use one of the predefined constants on this class.
* Alternatively, the {@link StandardToStringStyle} class can be used
* to set the individual settings. Thus most styles can be achieved
* without subclassing.
*
* If required, a subclass can override as many or as few of the
* methods as it requires. Each object type (from boolean
* to long to Object to int[]) has
* its own methods to output it. Most have two versions, detail and summary.
*
*
For example, the detail version of the array based methods will
* output the whole array, whereas the summary method will just output
* the array length.
*
* If you want to format the output of certain objects, such as dates, you
* must create a subclass and override a method.
*
* public class MyStyle extends ToStringStyle {
* protected void appendDetail(StringBuffer buffer, String fieldName, Object value) {
* if (value instanceof Date) {
* value = new SimpleDateFormat("yyyy-MM-dd").format(value);
* }
* buffer.append(value);
* }
* }
