从java编译中排除类的特定方法

Question

I want to exclude a particular method of a class from java compilation.

For eg:

class Test { 
       public void printdouble(){}
       public void printint(){}
 }

Depending upon some properties, I want to exclude printdouble method during compilation.

NOTE: I'm using ant script for java compilation

Thanks in Advance Soman

Answer 1

You need to use a form of conditional compilation to achieve this.

Here's a tutorial on how to do it with Ant.

Answer 2

如果您解释为什么要尝试排除该方法，我们可能会提供一个更好的解决方案，不涉及预处理，代码生成和其他“hacky”方法。

Answer 3

The only way to accomplish that in Java is some form of code generation or templating that generates the source code and then has Ant compile that.

If you describe what you want to accomplish you may find a more "Java" way to accomplish it.
