Activation - the time during which an object has a method executing. It is often indicated by a thin box or bar superimposed on the Object's lifeline in a Sequence Diagram; Activity diagram - a diagram that describes procedural logic, business process or work flow. An activity diagram contains a number of Activities and connected by Control ...
Activation boxes, or method-call boxes, are opaque rectangles drawn on top of lifelines to represent that processes are being performed in response to the message (ExecutionSpecifications in UML). Objects calling methods on themselves use messages and add new activation boxes on top of any others to indicate a further level of processing.
Although UML 2.1 was never released as a formal specification, versions 2.1.1 and 2.1.2 appeared in 2007, followed by UML 2.2 in February 2009. UML 2.3 was formally released in May 2010. [18] UML 2.4.1 was formally released in August 2011. [18] UML 2.5 was released in October 2012 as an "In progress" version and was officially released in June ...
In the Unified Modeling Language, an action [1] is a named element that is the fundamental unit of executable functionality. Actions take a set of inputs, which may be empty, and convert them to a set of outputs, which in turn may also be empty. [1] The execution of an action represents some transformation or processing in the modeled system.
Reading a communication diagram involves starting at message 1.0, and following the messages from object to object. Communication diagrams show much of the same information as sequence diagrams, but because of how the information is presented, some of it is easier to find in one diagram than the other.
Neurocomputational models of speech processing are complex. They comprise at least a cognitive part, a motor part and a sensory part. [2]The cognitive or linguistic part of a neurocomputational model of speech processing comprises the neural activation or generation of a phonemic representation on the side of speech production (e.g. neurocomputational and extended version of the Levelt model ...
Activity diagrams [1] are graphical representations of workflows of stepwise activities and actions [2] with support for choice, iteration, and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e., workflows), as well as the data flows intersecting with the related activities.
A sample UML class and sequence diagram for the Command design pattern. [3]In the above UML class diagram, the Invoker class doesn't implement a request directly. Instead, Invoker refers to the Command interface to perform a request (command.execute()), which makes the Invoker independent of how the request is performed.
