QuickLinks is one of the most used and useful features in defining domain-specific MDG technology. In addition, the latest version of Sparx Enterprise Architect 14 allows users to define rules for QuickLinker. Each rule has unique features like defined connectors between stereotypes, filtering in classifiers, defining stereotypes connectors between stereotypes and so on. Each rule can be created in the UML profile between the defined stereotypes.

Assuming you’ve good knowledge in Defining Customized MDG Technology, Let’s see in detail about defining QuickLink rules

Methods for defining QuickLink rules are Methods for defining QuickLink rules are

  • Meta-Constraint
  • Meta-Relationship
  • Stereotyped Relationship

Each of the above-mentioned types can be accessed by creating a connector between two defined stereotypes as shown below

          Untitled

Meta-Constraint

Meta-Constraint is used to specify a rule between two defined Stereotypes. The value should be assigned in the tag 'umlRole' on the connector created for meta-constraint.

To create Meta-Constraint

In the below example we are extending\generalizing two stereotypes named Object and Data from BPMN2.0 Activity. Creating a new meta-constraint with classifier filter between the created stereotypes. The created meta-constraint will be used to filter based on the target stereotype when selecting the classifier from the source stereotype.

  1. Draw a connector with meta-constraint stereotype between the two defined stereotypes

            Untitled0

  1. Navigate to the tags tab of the created connector and set one of the constraint values as shown below in the umlRole tag

            Untitled1

  1. Once saved the defined QuickLink constraint looks like below

          Untitled2

After importing the created profile/mdg in the model, when defining classifier for the element with stereotype Object enterprise architect will only show elements with stereotype as Data in the list (refer below)      Untitled3

 This is the process of defining meta-constraint in QuickLink. Above example illustrates with the constraint value\ umlRole as “classifier”.

For other types of constraint values refer below diagram from SPARX.

          Untitled 0.1

Meta-Relationship

Meta-Relationship is used to specify a valid UML Connector between two defined Stereotypes. The name of the UML Connector should be set in the value of tag 'metaclass' on the connector created for Meta-Relationship.

To create Meta- Relationship

In the below example we are extending\generalizing two stereotypes named Application and Function from BPMN2.0 Activity. Creating a new metarelation with generalization connector between the created stereotypes. The created metarelation will be used to create a generalization connector in quick links.

  1. Draw a connector with metarelation stereotype between the two defined stereotypes

           Untitled4.0

  1. To set the UML connector , Navigate to the tags tab of the created connector and set one of the UML Connector as shown below in the metaclass tag

           Untitled4.1

  1. Once saved the defined QuickLink constraint looks like below

           Untitled4

After importing the created profile/mdg in the model, the created UML connector will be displayed in the QuickLinker list when we try to create a QuickLink between these stereotyped elements application and function. It can be even defined as self-connector (refer below)

Untitled512

  This is the process of defining meta-relationship in QuickLink.

Stereotyped Relationship

Stereotyped Relationship is used to define a stereotyped connector between the two defined Stereotypes. The name of the stereotyped connector is set in the value of tag 'stereotype' on the connector created for Stereotyped Relationship.

To create Stereotyped Relationship

In the below example we are extending\generalizing two stereotypes named Mobile and Web from BPMN2.0 Activity. Creating a new stereotyped relationship between the created stereotypes. The created stereotyped relationship will be used to connect the target stereotype element with BPMN2.0 sequence flow.

  1. Draw a connector with stereotyped relationship stereotype between the two defined stereotypes

           Untitled6

  1. To set the connector stereotype, Navigate to the tags tab of the created connector and set one of the connector stereotypes in stereotype tag(It can be either a simple or a fully qualified connector stereotype )

           Untitled7

  1. Once saved the defined QuickLink constraint looks like below

           Untitled8

After importing the created profile/mdg in the model, the defined stereotyped connector will be displayed in the QuickLinker list when we try to create a QuickLink between these stereotyped elements (refer below)

Untitled910

This is the process of defining stereotyped-relationship in QuickLink.
