Engine Node The engine node corresponding to a C++ proc differs from the

version for the straight Java implementation in a variety of ways:

• The class does not implement

CNKProcJavaTransformExec.

•The

procCreate() method creates a Java class corresponding

to the C++ proc rather than registering the current class.

•There is no

execute() method.

It is similar in its imports, constructor, and the

calculateOutputMetaData() method.

The notable aspect of this code is the construction of the

CNKProcSecondCopy object in procCreate(). The rest of the code is

familiar from the previous example.

The

SecondCopyEngineNode.java file contains:

import com.insightful.miner.*;

import com.insightful.cnkjava.*;

/**

* Very simple implementation of engine node copying each

* input to the corresponding output using a C++ proc.

public class SecondCopyEngineNode extends EngineNode {

/**

* Empty constructor just uses the super method.

public SecondCopyEngineNode() {

}

/**

* Create the CNKProcSecondCopy object.

public CNKProc procCreate() throws Exception {

CNKProcSecondCopy proc = new CNKProcSecondCopy();

return(proc);

}
