/**
* <code>ToStringStyle</code> works with ToStringBuilder to create a
* toString. The main public interface is always via ToStringBuilder.
* <p>
* 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.
* <p>
* 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.
