Biases are either <EM>leading</EM> (the left edge, for a left-to-right character) or <EM>trailing</EM> (the right edge, for a left-to-right character). Instances of <code>TextHitInfo</code> are used to specify caret and insertion positions within text. <p> For example, consider the text "abc". TextHitInfo.trailing(1) corresponds to the right side of the 'b' in the text. <p> <code>TextHitInfo</code> is used primarily by <A HREF="../../../java/awt/font/TextLayout.html"><CODE>TextLayout</CODE></A> and clients of <code>TextLayout</code>. Clients of <code>TextLayout</code> query <code>TextHitInfo</code> instances for an insertion offset, where new text is inserted into the text model. The insertion offset is equal to the character position in the <code>TextHitInfo</code> if the bias is leading, and one character after if the bias is trailing. The insertion offset for TextHitInfo.trailing(1) is 2. <p> Sometimes it is convenient to construct a <code>TextHitInfo</code> with the same insertion offset as an existing one, but on the opposite character. The <code>getOtherHit</code> method constructs a new <code>TextHitInfo</code> with the same insertion offset as an existing one, with a hit on the character on the other side of the insertion offset. Calling <code>getOtherHit</code> on trailing(1) would return leading(2). In general, <code>getOtherHit</code> for trailing(n) returns leading(n+1) and <code>getOtherHit</code> for leading(n) returns trailing(n-1). <p> <strong>Example</strong>:<p> Converting a graphical point to an insertion point within a text model <blockquote><pre> TextLayout layout = ...; Point2D.Float hitPoint = ...; TextHitInfo hitInfo = layout.hitTestChar(hitPoint.x, hitPoint.y); int insPoint = hitInfo.getInsertionIndex(); // insPoint is relative to layout; may need to adjust for use // in a text model </pre></blockquote><P><DL><DT><B>See Also: </B><DD><A
