>From what I can see in sample code:
public class Point{}
public aspect Point
{
// a new method is introduced into the Point Class.
public String Point.toLongString(){
return "### FROM ASPECT ###";
}
}
public class Main{
public static void main(String[] args){
Point p1 = new Point();
// This line below works without any error.
System.out.println("p1.toLongString =" +p1.toLongString());
System.out.println("p1 =" + p1);
}
}
---------------------------------------------------------------
However, when I tried this, it does not work
// Extends the String class and provide other useful
public privileged aspect StringUtils {
public String java.lang.String.ltrim(){
return "TEST LTRIM";
}
public String java.lang.String.rtrim(){
return "TEST RTRIM";
}
}
public class Main {
public static void main(String[] args) {
String string="ABCDEFG";
// Complians with the error shown below
string=string.ltrim();
System.out.println(string);
}
}
---------------------------------------------------------
Exception in thread "main" java.lang.NoSuchMethodError:
java.lang.String.ltrim()Ljava/lang/String;
at
stringext.StringUtils.ajc$interMethodDispatch1$stringext_StringUtils$java_lang_String$ltrim(StringUtils.aj)
at stringext.Main.main(Main.java:11)
----------------------------------------------------------
Please help to show how this can be done properly. Many thanks in advance.
