public class OpConditional
extends Op2

Conditional execution - works with streamed execution and is known to safe to evaluate that way (no issues from nested optionals). For each element in the input stream, execute the expression (i.e. index-join it to the element in the input stream). If it matches, return those results. If it does not, return the input stream element.
