To put additional nodes in the folder, include the additional

ActivityNodeModel elements at the same level as the one above. For

multiple folders, include additional

ExplorerFolder elements at the

same level as the one above.

Save this description in a file named extension.iml in the extension

directory. An XML file with all three descriptions of the copy nodes is

available in the programming examples directory.

Try the Node If you have successfully compiled the code, placed it in a properly

located jar file, and created the XML description of the examples

library, you’ll now be able to try the new node.

Start Spotfire Miner. The Explorer should now have a page titled

Programming Examples containing a folder with the First Copy

Columns node. This node can be dragged onto the worksheet,

connected, and executed just like any of the built-in nodes.

Simple C++

Version

In the first implementation, we do the computation completely in

Java. Let’s now construct an implementation in C++. We will need a

Java class extending

EngineNode to calculate the meta data and create

the Java proc object, a Java class extending

CNKProc indicating the

C++ class to use, and a C++ class extending

CNKProc performing the

computation.

Note that

CNKProc is the name of both a Java class and a C++ class.

The C++ classes discussed in the section The TIBCO Spotfire

Pipeline on page 50 all have corresponding Java classes with the same

name and purpose.
