Control Flow

Controlling the flow

If then statement

The example below calls the isAdmin method on myObject to determine if an admin email should be sent.

if (myObject.isAdmin()) then {
  myObject.sendAdminEmail();
}

If then else statement

The example below calls the isAdmin method on myObject to determine if an admin email or a non-admin email needs to be sent.

if (myObject.isAdmin()) then {
  myObject.sendAdminEmail();
} else {
  myObkect.sendNonAdminEmail();
}

While statement

The example below calls the hasMoreItems method on myObject to determine whether or not it has more items and if it does it goes into the loop calling the removeItem method on myObject.

while (myObject.hasMoreItems()) {
  myObject.removeItem();
}

Do while statement

The example below calls the decrementTime method on myObject and then determines whether or not to terminate the loop by calling the isMoreThanOneYearOld method on myObject.

do {
  myObject.decrementTime();
} while (myObject.isMoreThanOneYearOld());

For statement

The example below first initializes i. And then for every iteration of the loop it determines if the loop needs to be entered by calling the isLessThan method on i and if it must be entered it calls the the tick method on myObject. And it completes the iteration by calling the incrementOne method on i. If the loop must not be entered it continues with any statement past the for statement.

for(i=0; i.lessThan(10); i.incrementOne()) {
  myObject.tick();
}
