Loop node dialog box

Loop nodes

A loop node is a structured activity node that represents a general loop.

The "Loop node" dialog box contains four tabs - "Properties", "Notes", "Tagged values" and "Stereotypes". For information on these standard dialog box tabs, please see "Standard dialog box tabs".

Key:

· "Name": This is the name of the loop node.

· "Must isolate": If true, this means that an object used inside the node cannot be accessed by an action outside the node until all the actions in the node are complete.

· "Is tested first": This specifies whether or not the test is performed before the first execution of the body. If false, the body is executed once before the test is performed.

· "Setup": This specifies the initialization expression of the loop.

· "Test": This specifies the test expression that controls the exit of the loop node.
