Re: [aspectj-users] Introducing static member variable - Static Cross cu

["Bhaskar Maddala" <maddalab@xxxxxxxxx>]

Thank you,

In the interest of someone else who would like to do something
similar, (comments welcome)

package boxes;

public class Foo {
    private String m_name;

    public Foo(String name) {
	m_name = name;
    }

    public String getName() {
	return m_name;
    }
}

package boxes;

public class Bar {
    private String m_name;

    public Bar(String name) {
	m_name = name;
    }

    public String getName() {
	return m_name;
    }
}

import java.util.logging.Logger;

public aspect FooBarLogger pertypewithin(boxes..*){
    private Logger m_logger;

    pointcut loggedmethods() : within(boxes..*) && execution (* *.*(..));

    after() : within(boxes..*) && staticinitialization(*){
	m_logger = Logger.getLogger(getWithinTypeName());
    }

    before() : loggedmethods(){
	m_logger.entering(thisJoinPointStaticPart.getClass().getName(),
thisJoinPointStaticPart.getSourceLocation().toString());
    }

    after() : loggedmethods(){
	m_logger.exiting(thisJoinPointStaticPart.getClass().getName(),
thisJoinPointStaticPart.getSourceLocation().toString());
    }
}
