This section describes the Extend Notation used in a UML Use Case Diagram. An Extend Notation presents an extension relation between two use cases where one acts as the base use case and the other acts as an add-on use case.
扩展(Extend) 扩展关系的标识法,带有箭头的虚线,附近带有关键字«扩展»(« extend »),和包含关系一样,扩展关系并不是一种依赖。扩展关系要传达的是,当目标端的用例,位于扩展关系的箭头端被触发时,源端的扩展用例可能选择性的执行,这意味着扩展关系目标端的用例自动完成(当满足触发条件时)。 扩展关系的信...
From UML 1.3, relationships between use cases can be expressed in three different ways: generalization, include, and extend relationships. An extend relationship defines those instances of a use case that may be augmented with some additional behavior defined in an extending use case. While, the ...
Conditionally include a where clause in linq query Configuration Error :The element 'buildProviders' cannot be defined below the application level. Configuration error authentication mode="Windows" Configuring IIS Failed - cannot read redirection.config confirm box alert from code behind Confirm Box In ...
However, it remains unclear to what extent they mainly constitute a feedforward processing step, or rather are continuously involved in a recurrent network together with higher-order areas. We found that the temporal window in which primary visual cortex is required for the detection of identical ...
Primary sensory areas constitute crucial nodes during perceptual decision making. However, it remains unclear to what extent they mainly constitute a feedforward processing step, or rather are continuously involved in a recurrent network together with hi
The methods for directly measuring ROS level include chemiluminescence assays, static oxidation-reduction potential, and fluorescent probes such as dichlorodihydrofluorescein (H2DCFDA) [82]. Moreover, the total antioxidant capacity (TAC) in seminal plasma and the total ROS level also are important ...
ASP.NET has detected data in the request that is potentially dangerous because it might include HTML markup or script. ASP.Net Identity - Logging out after session expiration ASP.net Identity Security Stamp and force logout ASP.NET identity use email instead of user name ASP.NET MVC - Base...
The controller may also include a ground bias circuit that provides a virtual ground so that a converter may operate at lower cell voltages. The battery may be a single-cell battery, a universal single-cell battery, a multiple-cell battery or a multiple-cell hybrid battery. ...
Also depicted in FIG. 2 is the switch304's control plane430. The control plane430comprises the key management database432, the authentication database434, and the accounting database436. In one embodiment, the key management database432may include a lightweight directory access protocol (LDAP) ...
