Java CNKProc The Java class extending CNKProc has two main responsibilities:

• Indicate the name and location of the C++ class.

• Provide a mechanism for exchanging property values with the

C++ class.

Since we have no properties to exchange, our class will just perform

the first task. The

createPeerObject() method indicates that our

C++ class will be named

CNKProcCppSecondCopy, and it will be in the

cnkcopy C++ library. The

CNKProcSecondCopy.java file contains:

import com.insightful.cnkjava.*;

/**

* Java class corresponding to C++ proc for Copy Columns

* example.

public class CNKProcSecondCopy extends CNKProc {

/**

* Default constructor does nothing.

public CNKProcSecondCopy() {

}

/**

* Specify that the C++ class is named

* CNKProcCppSecondCopy and that it is in the cnkcopy
