+ * TTextProcessor class.
+ *
+ * TTextProcessor is the base class for classes that process or transform
+ * text content into different forms. The text content to be processed
+ * is specified by {@link setText Text} property. If it is not set, the body
+ * content enclosed within the processor control will be processed and rendered.
+ * The body content includes static text strings and the rendering result
+ * of child controls.
+ *
+ * Note, all child classes must implement {@link processText} method.
