public class TextBuffer
extends java.lang.Object
implements java.io.Serializable
```
The TextBuffer class provides a convenience way to create Text object and RichText object.
The principal operations on a TextBuffer are the append, setTextStyle and setParagraphStyle methods. The append method is overloaded so as to accept data of any type. Each effectively converts a given datum to a text and then appends the text to the text buffer. The setTextStyle and setParagraphStyle methods set the current text style and paragraph style of the text buffer respectively. The text style is used for the converted text. The paragraph style is used when the data of the text buffer is converted to the rich text representation by the toRichText method.
