reflexion and enum

[mark smith]

hi

i use this code

if (getGlass().tickness.contains("4")...    

getGlass return an enum

is there a way to do that with reflexion?

thanks

Not sure what you are asking. Can you elaborate? enums are just objects, so the reflection library should work for them too.

this line of code is in a class X who extends Y

if (getGlass().tickness.contains("4")...      

this class Y have

private Glass glass;

Glass is an enum

so my question is how to be able to do the same thing then

 if (getGlass().tickness.contains("4")   

but with reflexion?

i tried

m = this.getClass().getMethod("getGlass");
			m.invoke(this)    

but i'm not able to access the field (tickness)

any idea?

Try...

Method m1 = this.getClass().getMethod("getGlass");   
Object o1 = m1.invoke(this);
Field f2 = o1.getClass().getField("tickness");
Object o2 = f2.get(o1);

BTW, if you know the exact method to execute, and the exact field to get, why do you need reflection? The way you are doing it now is much easier than using reflection.

thanks Henry Wong that work...

the method can change... not the field...

If the field doesn't change, then there is no reason to use reflection to get it... you can simply cast and dereference it.

Method m1 = this.getClass().getMethod("getGlass");   
Object o1 = m1.invoke(this);
Object o2 = ((Glass)o1).tickness;
