Action chart element.
Do While Loop is one of three "loop" blocks that are used to implement iterations. The other two are For Loop and While Loop.
For detailed information on Do While loop please refer here.
In "do while loop" you define some action or a sequence of actions using other action chart blocks. These actions are executed if the condition defined for this loop evaluates to true.
Do While Loop
resembles
While Loop
in many respects. The difference between "while loop" and "do while loop" is that the statement of a "do while loop" is always executed at least once, even if the specified expression evaluates to
false
the first time. Whereas in a "while loop", if the condition is
false
the first time the statement is never executed.
To insert "do while loop" into action chart
Do While Loop
from the
Actionchart
palette onto the diagram of agent. While moving the mouse over the graphical editor you will see insertion points of action chart(s) indicated with little blue circles. Release the mouse button over the insertion point where you want to place the
block. New "do while loop" block will be inserted into this place.
Condition – Boolean expression that will be evaluated to decide whether the action of the "do while loop" should be performed once more.
Label – You can add here some comments, explaining the meaning of this "do while loop". The comments will be shown inside the block instead of Java code corresponding to this loop.
Fill color – Sets the fill color for the element. Click inside the control and choose a color from the set of most used ones, or choose some custom color using the Colors dialog box.
