Advanced programming / Mapping native and Java data types |
When calling a Java™ method with an expression evaluating to a BYTE, the runtime system converts the BYTE handle to an instance of the com.fourjs.fgl.lang.FglByteBlob 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.FglByteBlob class.
The com.fourjs.fgl.lang.FglByteBlob class implements following:
Method | Description |
---|---|
String toString() |
Returns the HEX string representing the binary data. |
static void valueOf( String val) |
Creates a new FglByteBlob object from a String object representing the binary data in HEX format. |
public static void useByte(FglByteBlob b) throws ParseException { String s = b.toString(); ... }
IMPORT JAVA com.fourjs.fgl.lang.FglByteBlob MAIN DEFINE jbyte com.fourjs.fgl.lang.FglByteBlob LET jbyte = FglByteBlob.valueOf("0FA5617BDE") DISPLAY jbyte.toString() END MAIN
