MDWList APIs

A list of model elements is represented by the interface MDWList, which is an sub interface of java.util.List. It provides facilities to invoke scripts on each model element of this list.

MDWList enables to :

• concatenate script results :
  • into a String using concat(String scriptName)
  • into a MDWList using collect(String scriptName)
  
  
• filter MDWObject elements of this list based on script results :
  • select all elements that matches a condition using select(String scriptName, Object value)
  • detect the first element that matches a condition using detect(String scriptName, Object value)
  • reject all elements that matches a condition using reject(String scriptName, Object value)
  
  
• filter MDWObject elements of this list based on metatype using getInstances(String typeName)


• sort MDWObject elements of this list using sort(String scriptName)

Examples

Let's take an MDWList containing UML classes Customer, Bank and Account

Concatenates the name of each Class:

myList.concat("name")
// output example: "CustomerBankAccount"

Concatenates the name of each Class, separated by a comma:

myList.concat("name", ", ")
// output example: "Customer, Bank, Account"

Creates an MDWList of each Feature of each Class:

myList.collect("feature")
// output example: [name, address, zipcode, number]

Concatenates the name each Feature of each Class, separated by a comma:

myList.collect("feature").concat("name", ", ")
// output example: "name, address, zipcode, number"

Gets the feature named "zipcode":

myList.collect("feature").detect("name", "zipcode")
// output: zipcode

Gets the non-abstract classes:

myList.select("isAbstract", Boolean.FALSE)
// output example: [Customer, Account]

Concatenates the name of each Class, separated by a comma and sorted by name:

myList.sort("name").concat("name", ", ")
// output example: "Account, Bank, Customer"
