Class OldTextPiece

java.lang.Object

org.apache.poi.hwpf.model.PropertyNode<TextPiece>

org.apache.poi.hwpf.model.OldTextPiece

All Implemented Interfaces:

java.lang.Comparable< TextPiece>, Duplicatable

@Internal
public class OldTextPiece
extends TextPiece

Lightweight representation of a text piece. Works in the character domain, not the byte domain, so you need to have turned byte references into character references before getting here. (文本片段的轻量级表示。在字符域中工作，而不是在字节域中工作，因此您需要在到达这里之前将字节引用转换为字符引用。)
