Use a structured record that is specialized with the indexedRecord stereotype to access an indexed file.
This type of file uses an index to associate the value of a designated field in the record with the logical position of that record in the file.
At generation time, use a ResourceAssociation part to specify how you want an indexed record to be implemented for your target platform and to provide information about how the fileName property relates to a physical file. For more information, see the EGL Generation Guide.
For information about properties you can assign to an IndexedRecord definition, see IndexedRecord properties.
