When calling a Java™ method with an expression evaluating to a TEXT, the runtime system converts the TEXT handle to an instance of the com.fourjs.fgl.lang.FglTextBlob class implemented in FGLDIR/lib/fgl.jar. You can then manipulate the LOB from within the Java code.
You must add FGLDIR/lib/fgl.jar to the class path in order to compile Java code with com.fourjs.fgl.lang.FglTextBlob class.
The com.fourjs.fgl.lang.FglTextBlob class implements following:
| Method | Description | 
|---|---|
String toString()  | 
Converts the large text data to a simple String. | 
static void valueOf( String val)  | 
Creates a new FglTextBlob object from a String. | 
public static void useByte(FglTextBlob t) throws ParseException {
    String s = t.toString();
    ...
}
IMPORT JAVA com.fourjs.fgl.lang.FglTextBlob
MAIN
  DEFINE jtext com.fourjs.fgl.lang.FglTextBlob
  LET jtext = FglTextBlob.valueOf("abcdef..........")
  DISPLAY jtext.toString()
END MAIN
