The loop activity offers the ability to iterate over lists. There are three different loop types: While, For, and For..In.
A Loop variable name has to be defined for use inside the loop, the item from the list will be parsed in this variable for use.
Variables defined outside the loop are usable inside the loop. However, variables defined inside a loop are not usable outside the loop.
Within the loop itself, you have to define the (sub)flows.
Loop in flow
begin for var i := 0 to Max do begin var IsLoaded: Boolean; IsLoaded := True; var CustomerViewList: ICodolexList<Project.DataSource.Codolex.ICustomerView>; var SQL := 'SELECT CustomerView.* '+ sLineBreak + 'FROM CustomerView AS CustomerView ';
var Params: IDatabaseParams := TDatabaseParams.Create;
CustomerViewList := Project.DataSource.Codolex.CustomerViewDataBroker.GetList(SQL, Params); end; end; |
Resulting code
Break and Continue
Inside a loop, the break and continue activities can be used.
A break will stop the loop and continue the flow after the loop.
A continue will stop this iteration, and go to the next iteration if there is one available
Loop in flow
.. for var String in StringList do begin if (String = value = null) then begin Break; end else begin Continue; end; end; .. |
