Check Javadocabout Textclass. It has two methods: toString()and getValue().
But toString()returns first 70 characters only.
检查关于类的JavadocText。它有两种方法:toString()和getValue()。但只toString()返回前 70 个字符。
So, use getValue()instead:
因此,请getValue()改用:
String value = someText.getValue();
Contructor of the Textclass supports initialization with a string value. And (as Javadoc says), this object cannot be modified after construction.
Text类的构造函数支持使用字符串值进行初始化。并且(如 Javadoc 所说),该对象在构造后无法修改。
