LineBreakMeasurer Ja va 1.2

java.awt.font

This class breaks a paragraph of text into individual lines of a specified width, where

each line is repr esented by a TextLayout object. When you create a LineBreakMeasurer, you

must specify the paragraph to be broken with a java.text.AttributedCharacterIterator, which is

usually is obtained from a java.text.AttributedString.You may optionally specify a

java.text.BreakIterator to indicate where line breaks are allowed. The default is to use the

line breaking rules of the current locale. You must also pass a FontRenderContext to the

LineBreakMeasurer() constructor. The FontRenderContext is usually obtained with the get-

FontRenderContext() method of Graphics2D.

Once you have created a LineBreakMeasurer for your paragraph, you use it by repeatedly

calling nextLayout() to create TextLayout objects that repr esent lines. nextLayout() retur ns null

when it reaches the end of the paragraph. The desired width of each line is passed as

an argument to nextLayout(). This allows the first line of a paragraph to be made shorter

than the following lines, for example.

public final class LineBreakMeasurer {
