Dependency Matrix tool allows templates to access data from a Dependency Matrix, use diagrams to get data, row elements, column names, or relations between row and column elements from the matrix.

A Class diagram of the DependencyMatrixTool.

You can use the following Dependency Matrix tool API in the template.

Class DependencyMatrixTool

Use the following methods to use diagrams to get data.

• +getMatrix( diagram : Diagram) : Matrix
• +getMatrix( diagramName : String) : Matrix 

Class Matrix

Use the following methods to use diagrams to get row elements, column elements, and relations between row and column elements.

• +getRows() : List<Element>
• +getColumns() : List<Element> 
• +getRelation( row: Element, column : Element) : List<Relation> 

Class Relation

Use the following methods for class relations.

• +getName() : String
• +getElement() : Element 
• +getSemanticType() : String 
• +getDirection() : String

Using Diagrams to Get Data from Dependency Matrix

A Dependency Matrix is a special diagram. You can retrieve it using the $Diagram variable. Thus, every method must accept a diagram instance or a diagram’s name. Use the following methods to return a Dependency Matrix instance. You can retrieve rows and columns from the Dependency Matrix instances.

Getting Dependency Matrix Instances from Diagram Elements

getMatrix(diagram : Diagram) : Matrix
To get a Dependency Matrix instance from a specified diagram element, use the following code.

#set($matrix = $depmatrix.getMatrix($diagram))

Where the parameter is:

• diagram – a diagram element

Return an instance of Dependency Matrix.

For example:

#foreach($diagram in $project.getDiagrams("Dependency Matrix"))
#set($matrix = $depmatrix.getMatrix($diagram)) 
#end

Getting Dependency Matrix Instances from Diagram Names

getMatrix(diagramName : String) : Matrix
To get a Dependency Matrix instance from a specified diagram’s name.

#set($matrix = $depmatrix.getMatrix($diagram))

Where the parameter is: 

• diagram – a diagram’s name

Return a Dependency Matrix instance.

Example code:

#set($diagram = "diagram name")
#set($matrix = $depmatrix.getMatrix($diagram))

Getting Row Elements

The Matrix consists of rows and columns.

Getting All Row Elements

getRows() : List<Element>

Use this method to retrieve a list of row elements.

$matrix.getRows()

The returned value is a list of Elements.

To print all row elements' names, for example, type the following code:

#foreach($row in $matrix.rows) 
$row.name 
#end

Getting Column Elements

The matrix consists of rows and columns.

Getting all column elements

getColumns() : List<Element>

Use this method to retrieve a list of column elements.

$matrix.getColumns()

The returned value is a list of Elements.

To print all column elements' names, for example, type the following code:

#foreach($col in $matrix.columns) 
$col.name 
#end

Getting Relations between Row and Column Elements

getRelation(row : Element, column : Element) : List<Relation>

Use this method to retrieve the relations between row and column elements.

$matrix.getRelation($row, $column)

Where the parameter is:

• row – a row element
• column – a column element 

The returned value is a list of Relations.

The Relation class contains the following methods:

• getSemanticType : String
               Return the semantic type
• getElement : Element 
               Return a relationship element or null if the relationship is not an element, for example, tag name.
• getName : String 
               Return a relationship name. If the relationship is a tag name, it will return the tag name. If the relationship is NamedElement, it will return the element name;              otherwise, return a human name.
• getDirection : String 
               Return the direction.

To print the row, column, and its relationship name, for example, type the following code:

#foreach($row in $matrix.rows) 
   #foreach($col in $matrix.columns)
      #foreach($rel in $matrix.getRelation($row, $col))
         $row.name has $rel.name with $col.name
      #end
   #end
#end

To print rows, columns, and relations in a spreadsheet file format, for example, type the following code:

#import('depmatrix','com.nomagic.reportwizard.tools.DependencyMatrixTool')

#forpage ($diagram in $report.filterDiagram($Diagram,["Dependency Matrix"]))

#set($matrix=$depmatrix.getMatrix($diagram))

$bookmark.create($diagram.name)

#forcol ($col in $matrix.columns)$col.name#endcol

#forrow($row in $matrix.rows)$row.name

#forcol ($col in 

$matrix.columns)#if(!$report.isEmpty($matrix.getRelation 

($row,$col)))-> #end#endcol

#endrow

#endpage
