Function: break()
Within a do() or forEach() function break() causes the do() or forEach() functions to stop immediately and return a _NULL value.
If used outside of a do() or forEach() function then break() will cause the analysis for the Stream Set to stop as though a stop() function was called (but will produce an error message rather than a warning message). No records will be saved for that Stream Set.
Syntax
break()
Examples
forEach( $prefix, lookup.prefixes, if( stringLength($prefix) > 20, do ( debug("Stopping because prefix > 20"), break() ) ), $highest = $prefix )
In the above expression the forEach() function will check each prefix in turn until it finds a prefix length greater than 20 at which point a debug message will be printed out to the log and break() will be called which causes the loop to stop processing.
