eval
- the evaluator to be used for selecting targets.

Ends the current iteration. After the execution of this method, all subsequent operations will be applied on the iterated collection as a whole instead of in a by-element basis.

public Level1ListSelectedElementsOperator<I,T> exec(IFunction<? super T,? extends T> function)
ExecutableSelectedOperator
Executes the specified function on the target object, creating a new operator containing the result of the execution.
This function does not allow the operator target type to change because a selection ("if") has already been done on the target objects, and this would render the operator inconsistent (some objects would belong to a type and others to another type).

ReplaceableOperator
Replaces the current target object with the specified replacement.
