+/**
+ * This class represents a hyphen. A 'full' hyphen is made of 3 parts: the
+ * pre-break text, post-break text and no-break. If no line-break is generated
+ * at this position, the no-break text is used, otherwise, pre-break and
+ * post-break are used. Typically, pre-break is equal to the hyphen character
+ * and the others are empty. However, this general scheme allows support for
+ * cases in some languages where words change spelling if they're split across
+ * lines, like german's 'backen' which hyphenates 'bak-ken'. BTW, this comes
+ * from TeX.
+ * 
+ * This class has been taken from the Apache FOP project (http://xmlgraphics.apache.org/fop/). They have been slightly modified.
