#WHILE LOOP IN SEQUENCE DIAGRAM HOW TO#

In general, a test section may be executed in any order, including simultaneously if the underlying execution architecture supports it. If no test section yields a true value, then no body section is executed this may be a semantic error if output values are expected from a Conditional Node. The choice is nondeterministic unless the test sequence of clauses is specified.If more than one test section yields a true value, only one body section will be executed.If one or more test sections yield a true value, one of the corresponding body sections will be executed.When the Conditional Node begins execution, the test sections of the clauses are executed. The Sequence Node is created.Ī Conditional Node is a structured activity node representing an exclusive choice among a number of alternatives.Ī Conditional Node consists of one or more clauses, each consisting of a test section and a body section. Expand the Activity diagram palette, click the downward arrow button next to the Conditional Node/Loop Node/Sequence Node icon, and select Sequence Node from the shortcut menu.When combined with flows, actions must also satisfy their control and data flow inputs before starting execution. When the Sequence Node is enabled, its executable nodes are executed in the specified order. The Loop Node is created.Ī Sequence Node is a structured activity node that executes its actions in order. Expand the Activity diagram palette, click the downward arrow button next to the Conditional Node/Loop Node/Sequence Node icon, and select Loop Node from the shortcut menu.The results of the final execution of the test or body are available once the execution of the loop is completed.The body can contain actions to be executed repeatedly until the test produces a false value.The test section defines the loop exit-condition, it may precede or follow the body section.It is executed once on entry to the loop, and the test and body sections are executed repeatedly until the test produces a false value. The setup section usually initiates variables that are used in the loop's exit-condition.Each section is a well-nested subregion of an activity whose nodes follow any predecessors of the loop and precede any successors of the loop.

+->Īs usual, the class diagram doesn’t tell us enough information to understand what is happening, so let’s look at the sequence diagram of this pattern:Īdapter->Implementation:implementationMethod()Īs you can see, the adapter simply translates the parameters back and forth so the client and the implementation can communicate. The result would look something like this: It simply means that it replaces the existing implementation).

#WHILE LOOP IN SEQUENCE DIAGRAM HOW TO#

You have a client that know how to work with an existing class and you want to replace this class with a new implementation without having to change: 1) the functionality of the client (except maybe how he creates the class) and 2) Without changing the interface of your new implementation (because while I say here new, it doesn’t mean you wrote it. The class diagram of the Adapter patterns is pretty simple. And we could do the same for a GWT canvas! cool, right? But anyway, If you didn’t get this, let’s try one more time using UML class and sequence diagrams: So theoretically (and practically, since this is being done in the new version of draw2d), we could take an AWT canvas and wrap it so that it can be used with draw2d. In the current implementation, there is a class that takes the canvas and wraps it into a Canvas interface for use with draw2d. To work, draw2d only needs a Canvas on which it draws. This framework is build on top of SWT, but this is just because of historical reasons. One example where this pattern can be used is in the eclipse draw2d framwork. The Adapter (or Wrapper) design pattern is used when you want to adapt a class to an interface that it can implement.
