Complex Data Type Definitions

A complex data type definition represents the schema of the data. Use complex data type definitions to define the schema of the data for a struct port. If the complex port is of type struct or contains elements of type struct, you must specify the type configuration to reference a complex data type definition.

You can create or import complex data type definitions. You import complex data type definitions from complex files. Complex data type definitions are stored in the type definition library, which is a Model repository object.

When you create a mapping or a mapplet, the Developer tool creates a type definition library with the name Type_Definition_Library. You can view and rename the type definition library and the complex data type definitions in the Outline view of a mapping. The complex data type definitions appear on the type definition library tab of the mapping editor. The tab name is based on the name of the type definition library. You create or import complex data type definitions on the type definition library tab. When a mapping uses one or more mapplets, rename the type definition libraries in the mapping and the mapplets to ensure that the names are unique.

Type definition library and complex data type definitions are specific to a mapping or mapplet. A mapping or a mapplet can have one or more complex data type definitions. You can reference the same complex data type definition in one or more complex ports in the mapping or mapplet.

Complex Data Type Definition Example

The complex ports work_address and home_address of type struct have the following schema:

{street:string, city:string, state:string, zip:integer}

In the mapping, you create a complex data type definition typedef_adrs that defines the schema of the data. Then, you specify the type configuration of the struct ports work_address and home_address to use the typedef_adrs complex data type definition.

The following image shows a complex data type definition typedef_adrs:
