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 the following:
| Method | Description |
|---|---|
|
Dereferences the underlying TEXT variable. |
|
Converts the large text data to a simple
String. |
|
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 a
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
