BasicLineFormatter

• java.lang.Object

Fields Summary
public static final BasicLineFormatter	DEFAULT A default instance of this class, for use as default or fallback. Note that {@link BasicLineFormatter} is not a singleton, there can be many instances of the class itself and of derived classes. The instance here provides non-customized, default behavior.
