cniEvaluate
This function performs node processing. The integration node calls this function when a message is received on one of the input terminals of an instance of a node object.
The function forms the main logic of the message processing node or output node. It is not used with input nodes. You must define a function table before you call this function.
The responsibilities
of the node at this point are to:
- Process the message in accordance with the values of the attributes on the node instance.
- Process the message based on content, if desired.
- Propagate the message to any appropriate output terminals.
- Throw an exception if an error occurs.
