Using the TEXT type

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:

Table 1. Methods of the com.fourjs.fgl.lang.FglTextBlob class
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`.

In the Java code, you can pass a com.fourjs.fgl.lang.FglTextBlob object as in this example:

public static void useByte(FglTextBlob t) throws ParseException {
    String s = t.toString();
    ...
}

If you need to create an com.fourjs.fgl.lang.FglTextBlob object in your program, you can use the valueOf() class method as in this example:

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
