Examples of KnuthPenalty

org.apache.fop.layoutmgr.KnuthPenalty
An instance of this class represents information about a feasible breaking point; it does not represent any piece of content. A KnuthPenalty is a feasible breaking point unless its value is infinity; a KnuthPenalty whose value is -infinity represents a forced break. A KnuthPenalty is suppressed, and its width is ignored, if it is not a chosen breaking point; for example, a KnuthPenalty representing a hyphenation point has a width (the "-" width), which must be ignored if that point is not chosen as a breaking point. Besides the inherited methods and attributes, this class has two more attributes and the methods used to get them: the penalty value, which is a kind of "aesthetic cost" (the higher the value, the more unsightly the breaking point), and a boolean that marks KnuthPenalties which should not be chosen as breaking points for consecutive lines.
