How to .tml template access a class's static variable
I want to from B.tml access a static variable/method of A class but I don't
know how to... Help me please
RE: How to .tml template access a class's static variable
Posted by Alfie Kirkpatrick <Al...@ioko.com>.
Since it is public static can you not just have:
----------------- B.java ----------------------
public class B {
public String getNameOfA() {
return A.getName();
}
}
----------------- B.tml ----------------------
<div>${nameOfA}</div>
Or am I missing something? If it was not static you could @InjectPage A as a field in page B and access it that way?
Regards, Alfie.

I have a stable system, so I don't want to modify so much code. In addition,
your suggestion can cause the code duplicated and very hard to maintain.
I will make clear my idea: for example, I have A class
----------------- A.java ----------------------
public class A {
private static String name;
public static String getName() {
return name;
}
/*some method here*/
}
--------------------------------------------------
And from B.tml I want to get "name" value from getName() method. What should
I do now?

One question is how you expect to access the variable/method in the template and why you prefer to show/access so many static variable in the template?

Easy:
public class B {
public String getName() {
return A.getName();
}
}
Then use ${name} in your template.
