Create a Dynamic Model in Groovy

The Dynamic Model is an extension of the Managed Object Definition Language (MODEL).In this topic, you can find information about creating a dynamic model file in groovy.

A Model file in Groovy consists of the following:

• Domain: The domain to which a particular model file belongs. The domain is provided by adding the keyword domain followed by the domainName. Following is the list of supported domains and the corresponding domainName:

  Domain	Domain Name
  Network/IP/INCHARGE	Network
  Storage	vm
  Multicast	Mcast_Main
  Voip	Voip_Main
  MPLS	MPLS_Main
  NPM	BGP
  SAM	esm_sam

  To create a domain groovy, you can use the following code syntax:

  domain('Network') {
  
  }

• DomainClass: A domain class represents either a new class is added to the Model or a class to which new attributes or relationships are added. The following code syntax provides a new domainClass DM_Printer is added with the UnitaryComputersystem as a base class:

  domainClass('dm_Printer', UnitaryComputerSystem) {
  }

• Attributes: Adding attributes to a domainclass is defined by the stored keyword. The groovy dynamic model represents the topology view. Every attribute in the MODEL (mdl) file, irrespective of whether it is a computed, propagated, refined, instrumented, or stored attribute is defined in the groovy model as a stored attribute.
  The following example adds attributes to the earlier provided DM_Printer class:

  domainClass('NwtworkPrinter',UnitaryComputerSystem) {
  		stored DispName 
  		 
  	}

• Relationships: A new relationship can be added in the Groovy model to an existing or new domainClass. There are two ways in which a relationship can be added to a new domainClass:

  domainClass('NwtworkPrinter',UnitaryComputerSystem) {
  		//Relationship specifying a relationName and A targetclass  
  		relationship(ConnectionTo, Router) 
  }

  domainClass('NwtworkPrinter',UnitaryComputerSystem) {
              //Relationship specifying a relationName,targetclass and inverserelationship
  		relationship(ConnectionTo, Switch,ConnectionBy)  
  	}

Following is the example of a Groovy file:

def Model = {
     domain('Network') {
domainClass('DM_Printer',UnitaryComputerSystem) {
		stored DispName 
		relationship(ConnectionTo, Router) 
	}

      }
}
