Engine Node The engine node implementation displays a variety of functionality:

• Return the metadata for the specified columns.

• Store the column names before executing the proc for each

chunk, and delete these names after execution is complete.

• Print an information message and copy the selected columns

for each chunk.

• After execution, store the input metadata in a cache that can

be accessed later for viewing.

The code for this in the file

ThirdCopyEngineNode.java is:

import com.insightful.miner.*;

import com.insightful.cnkjava.*;

import java.util.Vector;

/**

* Extended implementation of engine node copying each

* input to the corresponding output. Assumes a single

* input and output. Stores the input metadata in a

* cache as an example of caching information for use

* in a viewer.
