Chapter 3 Getting Started with Objects Manipulation Using Scripts

Mapping Objects Using Scripts

You can use scripting to map objects from heterogeneous models.

You create or reuse a mapping for an object using the following method on the DataSource object and on the ClassifierMap object: CreateMapping(ByVal Object As BaseObject) As BaseObject.

Example

Given the following example where an OOM (oom1) contains a class (class_1) with two attributes (att1 and att2) and a PDM (pdm1) contains a table (table_1) with two columns (col1 and col2). To map the OOM class and attributes to the PDM table and columns, you have to do the following:

Create a data source in the OOM

set ds = oom1.datasources.createnew

Add the PDM as source for the data source

ds.AddSource pdm1

Create a mapping for class_1 and set this mapping as the default for class_1 (current data source being the default)

set map1 = ds.CreateMapping(class_1)

Add table_1 as source for class_1

map1.AddSource table_1

Add a mapping for att1

set attmap1 = map1.CreateMapping(att1)

Set col1 as source for att1

attmap1.AddSource col1

Add a mapping for att2

set attmap2 = map1.CreateMapping(att2)

Set col2 as source for att2

attmap.AddSource col2

You can also get the mapping of an object using the following method on the DataSource object and on the ClassifierMap object: GetMapping(ByVal Object As BaseObject) As BaseObject.

Get the mapping of class_1

Set mymap = ds.GetMapping (class_1)

Get the mapping of att1

Set mymap = map1.GetMapping (att1)

For more information about objects mapping, see the "Mapping objects"section in the "Working with" chapter in the OOM, the PDM and the XSM user's guides.
