Spy Operator

Basic Node Parameter

Spy Operator

The Result and Spy nodes are troubleshooting tools. Result displays, in the node itself, the value at its input port. The Spy node passes the value to its output port rather than displaying it.

You can check the output of any element by connecting it to a Result or Spy node. The Result node has an input only while the Spy node has an input and an output. Use the Result node if you don’t need to pass the value on to another element, otherwise use the Spy node and connect it between the two elements. Set the data type for the Result or Spy node in the Attribute Manager.

Result and Spy nodes slow down the expression. Therefore you should delete them as soon as they are no longer required.
