Evaluating Expressions

Evaluating Expressions

When the Debugger pauses, use the Expression Editor to evaluate expressions using mapping variables and ports in a selected transformation.
You can evaluate expressions in the following transformations:
  • Aggregator transformation
  • Expression transformation
  • Filter transformation
  • Rank transformation
  • Router transformation
  • Update Strategy transformation
When you create an expression, you use references to ports within the transformation. The Expression Editor does not display ports for other transformations in the mapping. When you evaluate the expression, the Debugger returns the result of the expression in a message box.
