RE: Override dependency classes with another module's classes

[Brendan Haverlock]

Martin,

 

Unfortunately, we are overriding classes from a dependency library, so we
are just putting the classes in the same package and wanting our overriding
classes to get precedence on the classpath.  So, our classes are in the same
package as the library's classes and have the same class name, we just want
ours to be used at compile time.

 

Thanks,  

 

Brendan Haverlock

public interface ModuleC {
 public int doCalculationC(int a)
 {
   return(a+1);
  }
}
public class ModuleA implements ModuleC {
 public int doCalculationA(int a)
 {
   return (a+2);
 }
 public int doCalculationC(int a)
 {
   return(a+1);
  }
}
1. I have a Module A that is overriding a few, but not all, classes from its
> Dependency C.
//B extends A and all protected/public methods from A
//B implements C and all protected/public methods from C
public class ModuleB extends ModuleA implements ModuleC
{
  public int doCalculationB(int a)
  {
    return (a+3);
  }
public int doCalculationA(int a)
 {
   return (a+2);
 }
 public int doCalculationC(int a)
 {
   return(a+1);
  }
}
