java.lang.Object

org.luwrain.util.TextAligning

public class TextAligning
extends Object

Splits a text preserving lenth of lines not exceeding some given number. This class takes a set of lines and makes new dividing trying to make the length of each line close to some value as much as it is possible. The dividing is performed only on space characters ( Character.isSpaceChar()), so in common sense there is no guarantee that all lines will have the length not greater of the given value, because very long words go without splitting. If the position of the hot point is provided, it is moved to the corresponding place in the new lines.
